In short: the agency whose name is on the search result — SIT, the Superintendencia de Telecomunicaciones — is not your complaint route, and its own founding statute says so. Art. 78 of Decreto 94-96 sends operator-versus-user disputes to the courts. SIT’s eight statutory functions (Art. 7) contain exactly one dispute power and it is limited to disputes between operators. The route that works is DIACO — the government’s service catalogue prices that trámite at Q 0 — it accepts a passport, and it owes you a hearing date within ten days. This page is general information, not legal advice.
If your fiber has been down for a week, or your 500 Mbps plan delivers 40, the instinct is to find the regulator. Guatemala has one, it is called SIT, and English-language advice routinely tells you to complain there. That advice is wrong, and it is wrong in a specific, checkable way: the telecommunications law that created SIT deliberately did not give it a retail-customer jurisdiction. Knowing that saves you the two weeks most people lose finding it out.
What SIT is, and what it is allowed to do
Art. 5 of Decreto 94-96 creates it as “un organismo eminentemente técnico del Ministerio de Comunicaciones, Transporte y Obras Públicas” — an eminently technical body. Art. 7 then lists its functions, and the list is closed. All eight, as the statute prints them:
| # | Function (VERBATIM, Art. 7) | Is it about you? |
|---|---|---|
| a) | “Crear, emitir, reformar y derogar sus disposiciones internas” | No — internal rulemaking |
| b) | “Administrar y supervisar la explotación del espectro radioeléctrico” | No — spectrum |
| c) | “Administrar el Registro de Telecomunicaciones” | No — an operator registry |
| d) | “Dirimir las controversias entre los operadores surgidas por el acceso a recursos esenciales” | No — operator-vs-operator only |
| e) | “Elaborar y administrar el Plan Nacional de Numeración” | No — phone numbering |
| f) | “Aplicar, cuando sea procedente, las sanciones contempladas en la presente ley” | Only for breaches of this law |
| g) | Represent the country at international telecom bodies | No |
| h) | “Velar por el cumplimiento de esta ley y demás disposiciones aplicables” | General, not a complaint desk |

Literal d) is the only dispute-resolution power in the list, and the words entre los operadores are in the statute, not added here. A customer is not an operator: Art. 2 defines the term — “se denomina operador a toda persona, individual o jurídica que posee y administra una red de telecomunicaciones” — someone who owns and runs a network.
Art. 78 is the article that settles it
Title VI of the law is headed “SOLUCION DE CONFLICTOS ENTRE PARTICULARES” and contains a single article:
“ARTICULO 78. PROCEDIMIENTOS JUDICIALES. Cualquier conflicto que surja entre particulares, ya sea entre operadores o entre operadores y sus usuarios, en materia de telecomunicaciones, deberá ser resuelto por las partes a través de los procedimientos judiciales previstos en las leyes respectivas. Sin embargo, en ese tipo de conflictos las partes podrán utilizar métodos alternativos para la resolución de los mismos, tales como la conciliación o el arbitraje.”
Asked what happens when an operator and its user fall out, Guatemala’s telecom law answers: the courts — or conciliation or arbitration if you both agree. Two further articles, 78 bis and 78 ter, were added in 2003 and repealed in full by Art. 36 of Decreto 8-2013 on 9 October 2013; the consolidated text marks both “DEROGADO”.
What the law does not say — and this is the part that changes your expectations
We extracted all 47 pages of the consolidated statute and searched the text on 2026-09-17:
| Term searched | Occurrences | Where |
|---|---|---|
queja | 0 | — |
denuncia | 2 | Both inside Art. 53, radio interference |
reclam | 1 | Art. 89, “la resolución reclamada en la vía contencioso administrativa” — appealing a SIT ruling |
calidad | 5 | Arts. 27–28 (operator-to-operator access), Art. 57 (security paper for frequency titles), Art. 74 (state auction specs) |
conciliaci | 1 | Art. 78 |
Method: full text extracted from the published PDF, whitespace normalised, case-insensitive search, 2026-09-17.
There is no minimum speed, no uptime floor, no latency ceiling and no service-level standard owed to a retail subscriber anywhere in the statute. That is not an oversight you can appeal; it is the design of a liberalised 1996 telecom regime. Practically, it means the document that defines what you are owed is your contract, and the body that enforces contracts against providers is the consumer regulator — not the telecom regulator.
The one complaint SIT does take
Art. 53 is headed Protección contra interferencias, and it opens:
“Las personas individuales o jurídicas que posean títulos de usufructo de frecuencias y que en algún momento sufran interferencias radioeléctricas, podrán denunciarlas a la Superintendencia, proporcionándole un informe técnico emitido por una entidad acreditada por la misma para la supervisión del uso del espectro radioeléctrico.”
The accused party then has ten days to answer and SIT must rule within ten days after that. If you hold a frequency licence and someone is stepping on it, that is your route. If you have a router, it is not.
SIT’s own website confirms the gap
Read on 2026-09-17, sit.gob.gt’s complete public menu covers Misión y Visión, Normativas, Autoridades, Noticias, the three Gerencias, operator categories (ORC / ORL / OPI), numbering ranges, signalling, telephony statistics, satellite and terrestrial systems, frequency bands, RIABAP, the national frequency allocation table, broadcasting, radio amateurs, spectrum supervision, homologation, procedures, statistics, the two registries, the national digital connectivity plan, IMEI lookup, electronic services and publications.
No item on that menu is a consumer complaint route. Three URLs that search engines still return as SIT’s complaint system, FAQ and forms pages were all dead on the same date:
| URL search engines still return | Status, 2026-09-17 |
|---|---|
sit.gob.gt/servicios-en-linea/denuncias/ (“Sistema de Denuncias”) | 404 |
sit.gob.gt/preguntas-frecuentes/ | 404 |
sit.gob.gt/formularios-de-tramites-superintendencia-de-telecomunicaciones/ | 404 |
servicios.sit.gob.gt/portal (Portal de Trámites Electrónicos) | 200 — live, but a trámite portal, not a complaint desk |
SIT’s Procedimientos page states its own scope in one sentence: “Con el fin de informar a los interesados sobre los pormenores de trámites que siguen las solicitudes más comunes relacionadas con frecuencias radioeléctricas…” — procedures for frequency applications. Its Preguntas Jurídicas page opens on "¿Qué recursos proceden contra las resoluciones emitidas por el Superintendente de Telecomunicaciones?" and stays on frequency authorisations throughout.
SIT is still worth knowing for what it is good for: 6a Avenida 1-22 zona 4, Ciudad de Guatemala, PBX +502 2321-1000, plus the IMEI lookup — which is the tool you want after a phone theft, a different problem with a different route.
The route that works: DIACO
Decreto 6-2003, the Ley de Protección al Consumidor y Usuario, applies to “todos los actos jurídicos que se realicen entre proveedores y consumidores y/o usuarios dentro del territorio nacional” (Art. 2). The same article carries the clause lawyers will point at — sectors with their own specific legislation and their own controlling organ are governed by those norms, “aplicándose esta Ley en forma supletoria”, supplementarily. Telecom does have a specific law and a controlling organ. But that specific law, at Art. 78, expressly declines the dispute and sends it elsewhere — so the consumer statute is what is left standing. Reading the two statutes together is our reading, not a quotation; the quotations above are the parts you can check.
How to file
Two things first, both from the government’s own service catalogue entry for the trámite “Recepción y atención de quejas del consumidor” (tramites.gob.gt, retrieved 2026-09-17):
| VERBATIM | |
|---|---|
| Which ministry | “Ministerio de Economía -MINECO-” |
| What it costs | “Costo: Q 0” |
| Published duration | “12 días hábiles en la primera etapa administrativa del expediente (conciliatoria). En segunda etapa, audiencia 30 días hábiles. La duración del proceso dependerá de cómo se desarrolle cada caso después de la segunda audiencia.” |
Note that the catalogue’s clock and the statute’s clock measure different things: Art. 88’s ten days is the deadline to schedule the first hearing, while the catalogue’s 12 working days is the first administrative stage end to end. Both are printed here as each source states them.
DIACO publishes four channels (retrieved 2026-09-17):
| Channel | Detail (VERBATIM) |
|---|---|
| Phone | “Centro de llamadas 1544” |
| Web | “Página web www.diaco.gob.gt” |
| In person | “6ta Avenida 0-35 Zona 4 Centro Comercial Plaza 4, Oficina 401. Área de Restaurantes 3er Nivel, teléfono 2501-9600” |
| Departmental | “En cualquiera de nuestras sedes departamentales” |
The full step-by-step walkthrough — conciliation, timelines, common mistakes — is already on this site: Denuncia DIACO Guatemala. What follows is only what a foreigner with an ISP problem needs on top of it.
The two deadlines that actually decide your case
| Clock | Rule | Source |
|---|---|---|
| 5 working days — yours | “en un plazo no mayor de 5 días hábiles envíe por correo electrónico, identificado con su número de queja, copia de su dpi y copia de la constancia con la cual acredita su queja” | DIACO, Trámite de Queja, retrieved 2026-09-17 |
| 10 days — theirs | DIACO must set the hearing “señalando día y hora para la audiencia administrativa, dentro de los diez días siguientes a la fecha en que se presentó la queja” | Decreto 6-2003, Art. 88 |
| 10 days — the provider’s | “plazo de diez días, para que el supuesto infractor aporte sus pruebas de descargo” | Decreto 6-2003, Art. 92 |
| 3 years — the outer limit | “prescriben por el transcurso del plazo de tres años, los que principian a contarse a partir de la fecha en que se cometió la infracción” | Decreto 6-2003, Art. 104 |
Most complaints that die, die on the first row. You call 1544, you get a case number, and then the evidence email never goes out.
What a foreigner specifically needs to know
- A passport works. DIACO’s requirements read “Copia simple del Documento Personal de Identificación del propietario o representante legal o pasaporte, según sea el caso”.
- The paperwork must be in your name. “La documentación que acredita la queja deberá estar a nombre de la persona que la interpone.” If the internet contract is in the landlord’s name — very common on furnished rentals — the complaint belongs to the landlord.
- You can be represented. Art. 85: consumers and providers alike “podrán acudir ante la Dirección en nombre propio o por medio de sus representantes legales”.
- Your employer must let you attend. Art. 81 requires an employer to grant leave for a personally-summoned hearing, against DIACO’s written citation.
- DIACO cites its own legal basis as “los artículos 85 y 86 del Decreto 006-2003… y artículos 48, 50 del Reglamento Acuerdo Gubernativo 777-2003”. We quote DIACO’s citation; we did not read the Reglamento’s text.
The three provisions to actually cite in your complaint
Decreto 6-2003 gives you specific hooks. Quote the article number — it changes the tone of the hearing.
| Your situation | Provision | VERBATIM text |
|---|---|---|
| Billed for days the service was dead | Art. 16 h) | “Cobrar por un servicio que no se ha prestado, o que no se ha prestado en su totalidad, o no se ha demostrado que se ha prestado mediante la factura correspondiente” — prohibited |
| Charged more than the advertised price | Art. 16 a) | “El cobro de un precio superior al exhibido, informado o publicado” — prohibited |
| Sold on speeds the plan never delivers | Art. 4 d) | You have a right to “La información veraz, suficiente, clara y oportuna sobre los bienes y servicios” — and the same literal extends it to “sus precios, características, calidades, contenido y riesgos que eventualmente pudieren presentar” |
| Want money back, not an apology | Art. 4 e) | Right to “La reparación, indemnización, devolución de dinero o cambio del bien por incumplimiento de lo convenido” |
| Got less than you contracted for | Art. 4 f) | Right to “la devolución del precio que se haya pagado en exceso, cuando la calidad o cantidad sea inferior a la indicada” |
| Price changed mid-contract | Art. 47 a) and b) | In a contrato de adhesión, clauses letting one side modify the contract “a su solo arbitrio”, or adding “recargos no previstos”, produce no effect |
| Contract blames you for their outage | Art. 47 c) | Clauses that “Hagan responsable al consumidor o usuario por los efectos de las deficiencias, omisiones o errores del bien o servicio” produce no effect |
Before DIACO: the libro de quejas
Art. 17 obliges every provider to keep one, visibly:
“A efecto de garantizar el derecho de reclamo de los consumidores y usuarios, todo proveedor deberá poner a disposición de los mismos en un lugar visible, un libro de quejas o cualquier medio autorizado por la Dirección de Atención y Asistencia al Consumidor, el cual deberá ser de acceso irrestricto al público…”
Art. 4 j) makes using it your right. And Art. 16 makes two separate infractions out of obstructing it: literal m), “No proveer el libro de quejas”, and literal n), impeding access to it — which closes with the flat sentence “En ningún caso se puede negar al consumidor o usuario el derecho a inscribir sus reclamos.”
Practically: walk into the Tigo or Claro branch, ask for el libro de quejas, write the entry, and photograph your own entry with the date visible. That photograph is the “constancia” you email DIACO inside five working days. The trámite for authorising and replacing that book is a real procedure with its own file — see MINECO libro de quejas authorisation — which tells you the obligation is enforced, not decorative. Adhesion contracts have their own approval route too: MINECO adhesion contracts.
What none of this can get you
Being straight about the ceiling, because it determines whether the effort is worth it:
- Nobody can order your ISP to make the internet faster. No speed standard exists to enforce
(see the
calidadsearch above). The remedies in Decreto 6-2003 are money and contract remedies — refunds, indemnification, void clauses — plus sanctions payable to the state. - Sanctions go to the state, not to you. Art. 102: fines “ingresarán a los fondos privativos de la Dirección, para promover la educación al consumidor.”
- One fine per event. Art. 101: “cuando un mismo hecho constituya más de una infracción, se aplicará la sanción de mayor valor.”
- Conciliation ends it. Art. 103 d) lists conciliation as a way responsibility is extinguished. If you settle at the hearing, that is the end of the file.
- We do not publish fine amounts. Decreto 94-96 Art. 80 defers SIT’s fine scale to internal unidades de multa whose value is not in the statute, and no DIACO fine figure was verified from a primary source on 2026-09-17. Anyone quoting you a number should be asked for theirs.
The honest decision
| If your problem is… | Go to |
|---|---|
| Billing for a dead line, a surprise charge, a plan that is not what was sold | DIACO — catalogued at Q 0, 1544, hearing scheduled within 10 days |
| A slow connection that matches your contract’s fine print | Nobody. Change providers — see Guatemala internet: 5 ISPs tested and Starlink in Guatemala |
| Radio interference on a frequency you hold a title to | SIT, Art. 53, with an accredited technical report |
| A stolen phone you want blocked | SIT’s IMEI lookup plus your carrier — a different procedure |
| Money at stake big enough to litigate | The courts, per Art. 78 — or conciliation/arbitration if the operator agrees |
The realistic play for most remote workers is neither: keep a second connection. Outage-tolerance is cheaper than enforcement in a country whose telecom statute never promised you uptime. See what a UPS actually buys you and internet speed by region.

Frequently Asked Questions
Can I file a complaint against my internet provider with SIT in Guatemala?
Not as a retail customer. The Ley General de Telecomunicaciones (Decreto 94-96) lists SIT’s functions in Art. 7 and there are exactly eight of them — internal rules, spectrum administration, the Telecommunications Registry, the numbering plan, international representation, applying the sanctions the law contemplates, enforcing the law, and one dispute-resolution power. That dispute power, literal d), reads ‘Dirimir las controversias entre los operadores surgidas por el acceso a recursos esenciales’ — it is limited on its face to disputes between operators over access to essential resources. Art. 78 then deals with your situation directly: ‘Cualquier conflicto que surja entre particulares, ya sea entre operadores o entre operadores y sus usuarios, en materia de telecomunicaciones, deberá ser resuelto por las partes a través de los procedimientos judiciales previstos en las leyes respectivas’ — user-versus-operator conflicts go to the courts, or to conciliation or arbitration if both sides agree. We searched the full consolidated text of the law on 2026-09-17: the word queja appears zero times.
Then where do I actually complain about slow or dead internet in Guatemala?
DIACO, the Dirección de Atención y Asistencia al Consumidor. The government’s own service catalogue at tramites.gob.gt lists the trámite ‘Recepción y atención de quejas del consumidor’ under ‘Ministerio de Economía -MINECO-’ and gives its cost as ‘Costo: Q 0’. DIACO publishes four channels: the 1544 call centre, its website www.diaco.gob.gt, in person at 6a Avenida 0-35 Zona 4, Centro Comercial Plaza 4, Oficina 401 (telephone 2501-9600), and any of its departmental offices. The legal hook is Decreto 6-2003, the Ley de Protección al Consumidor y Usuario, whose Art. 16 literal h) prohibits a provider from ‘Cobrar por un servicio que no se ha prestado, o que no se ha prestado en su totalidad’ — charging for a service that was not delivered, or not delivered in full. Our step-by-step walkthrough of the DIACO procedure lives at /tramites/diaco-denuncia/.
Can a foreigner file a DIACO complaint without a Guatemalan DPI?
Yes. DIACO’s own published requirements list, retrieved 2026-09-17, reads ‘Copia simple del Documento Personal de Identificación del propietario o representante legal o pasaporte, según sea el caso’ — a passport is expressly accepted in place of a DPI. The harder requirement is the next observation on the same page: ‘La documentación que acredita la queja deberá estar a nombre de la persona que la interpone.’ The invoice or contract has to be in your name. If the internet account is in your landlord’s name, the complaint is your landlord’s to file, not yours.
Does Guatemalan law guarantee a minimum internet speed?
No such guarantee was found. We extracted the full consolidated text of Decreto 94-96 and searched it on 2026-09-17: the word calidad appears five times and not one of them is about what an operator owes a retail customer. Three are about operator-to-operator access — Arts. 27 and 28 require access to essential and additional resources to be given ‘con la calidad y en los nodos solicitados’. One is about the security paper that frequency titles are printed on (Art. 57). One is about the specifications published when the state auctions a subsidised project (Art. 74). There is no article setting a minimum speed, an uptime floor, a latency ceiling or a service-level standard owed to you. What you are owed is what your own contract says — which is why the contract, not the regulation, is the document that matters.
How fast does DIACO have to act once I file?
Decreto 6-2003 Art. 88 sets the clock: DIACO ‘citará al presunto infractor y al consumidor o usuario que presentó el reclamo, señalando día y hora para la audiencia administrativa, dentro de los diez días siguientes a la fecha en que se presentó la queja’. Ten days from filing to the scheduled hearing. Separately, DIACO’s own published guidance imposes a deadline on you: ’en un plazo no mayor de 5 días hábiles envíe por correo electrónico, identificado con su número de queja, copia de su dpi y copia de la constancia con la cual acredita su queja’. Five working days to email your evidence, or the file stalls.
Is there any complaint SIT does take?
One, and it is almost certainly not yours. Art. 53 of Decreto 94-96, ‘Protección contra interferencias’, lets holders of frequency usufruct titles report radio interference to SIT, and it requires a technical report from an entity accredited by SIT. The alleged causer then has ten days to answer and SIT must rule within ten days of that. That is a licensed-broadcaster remedy. SIT’s public website, read on 2026-09-17, carries no consumer complaint route anywhere in its menu — and the URL that search engines still return as SIT’s ‘Sistema de Denuncias’, sit.gob.gt/servicios-en-linea/denuncias/, returns HTTP 404.
My provider changed my price mid-contract. Is that allowed?
Your contract with Tigo, Claro or any ISP is a contrato de adhesión — terms set unilaterally, take it or leave it — and Decreto 6-2003 Art. 47 strips certain clauses of any effect in that kind of contract. Literal a) voids clauses that give one party the power ‘de dejar sin efecto o modificar a su solo arbitrio el contrato’. Literal b) voids clauses that set ‘incrementos de precio del bien o servicio por accesorios, financiamiento o recargos no previstos’. Literal c) voids clauses that make you responsible for the provider’s own deficiencies, omissions or errors. We have not read any specific operator’s contract, so this page states the rule, not its application to your bill.
