Thailand’s NBTC — Telecom Complaints and Consumer Rights
Thailand’s regulator for spectrum, telecoms and broadcasting — and where a complaint goes when your mobile or internet provider will not put things right.

What you can do
-
Billing disputes
A bill far above normal, an amount that does not match the package you agreed to, or a duplicated charge — all of these are disputable, and escalate to the regulator if the operator will not fix them.
-
Charges you never agreed to
A recurring charge for something you never knowingly signed up for, or signed up for without ever being told the price, is one of the most common complaints of all.
-
The right to know, the right to cancel
A licensed operator has to make terms and costs clear before it charges you, and has to make cancelling an unwanted service something you can actually complete.
-
Coverage quality and keeping your number
Service that keeps dropping inside an area advertised as covered, speeds well below what was promised, or a number transfer that fails again and again are all grounds for a complaint.
-
SIMs tied to your ID card
Every Thai mobile number is registered against a person’s identity — which also means a number someone else opened in your name traces back to you. Worth checking at least once.
-
Broadcast content
Alongside telecoms, the same body regulates radio and television, so complaints about programmes and advertising that go to air belong here too.
What the NBTC is, and what it does for you
The National Broadcasting and Telecommunications Commission — กสทช. in everyday Thai — allocates spectrum, licenses the mobile operators, the internet providers and the radio and television stations, and writes the rules every licence holder has to follow. Most of that work is policy, at a distance from daily life.
The other half is much closer to home: it receives complaints from the people who use those services. When an operator, an ISP or a broadcaster will not resolve something, the matter can be escalated to the regulator, because those companies hold licences and are bound by the conditions attached to them. In practice this is what gives the phrase “consumer rights” any weight at all, instead of leaving it to end in an argument with a call-centre agent that you eventually abandon.
The kinds of problem it takes
The scope runs across both telecoms and broadcasting. The table below sets out the common groups, with the evidence worth having in hand before you start.
| Type of problem | What it looks like | Evidence to keep |
|---|---|---|
| Billing | A bill far above normal, a duplicated charge, or an amount that does not match the agreed package | Recent bills, a screenshot of the package you signed up for, and the dates involved |
| Charges without clear consent | A monthly charge for something you never confirmed, or that you accepted without being told it cost anything | The activation message, the charge lines, and the outcome of your cancellation request |
| Cancellation that never completes | Billing continues after you cancelled, or you are passed between channels until the request dies | When you cancelled, through which channel, and the operator’s case number |
| Number portability | Repeated failures, refusals with no reason given, or a number that goes dead mid-transfer | Transfer-result messages, the request date, and the reason the operator gave |
| Coverage and speed | Service that keeps dropping inside an area sold as covered, or speeds far below those advertised | Timestamped speed tests, the address where it happens, and the earlier case number |
| Broadcast content | A programme or advertisement you consider improper or misleading | The channel, the programme, and the date and time it aired |
The order that matters: operator first, regulator second
The step people skip — and the reason their case stalls — is going to the regulator without ever having told the operator. Regulation of this kind starts from the premise that the company has already had its chance, so a complaint should always begin with the provider you are actually with. The one thing not to leave that conversation without is a case or reference number, along with the date, the time and the name of whoever took it: that is your proof the operator was given its chance, and it is usually the first thing asked for when you escalate. If the call centre will not issue one, record when you called, the number you dialled and a summary of what you were told.
The principles a complaint rests on
- You are entitled to know the price and the terms clearly before you are charged — not afterwards, when the amount shows up on the bill.
- A charge has to rest on the user’s consent. Tapping a button without being told it costs money, or an automatic renewal nobody mentioned, is not clear consent.
- You have the right to cancel a service you no longer want, and cancelling has to be something you can complete — not a loop designed to outlast your patience.
- You are entitled to a bill itemised well enough to check, and entitled to dispute a figure you believe is wrong.
- You are entitled to the quality of service that was advertised to you or written into the contract.
The SIMs registered in your name — worth checking once
Every mobile number in Thailand has to be registered against the identity of its user — a rule the regulator maintains together with the operators. Its virtue is that any number can be traced back to a person. Its other edge is that if someone opens a line using a copy of your ID card, that line stands in your name, and if it is then used for something criminal, yours is the first name any investigation meets. That is reason enough to check, at least once, how many numbers sit under your ID: each operator has its own route to look and to cancel a line you did not open, and because the picture is pooled nowhere, you have to check operator by operator.
Why a findable page has to point here
Nobody in the middle of a billing fight searches for “national telecommunications regulator”. They type “charged for something I never subscribed to” or “cannot cancel this add-on”, and what surfaces first is usually an old forum thread pulling in three directions. That gap — between the words people actually use and the name of the body with the power to act — is why this page starts where it does. Our check on 27 August 2026 adds a second reason. The site serves robots.txt normally — the one thing anyone can verify from outside, since that file is public and identical for every requester — but answers the pages themselves with a Cloudflare challenge that only clears once JavaScript has run. Ordinary browsers get through it, and Cloudflare normally waves verified search-engine crawlers past, so Google most likely reaches the site perfectly well; the refusal our audit host met, even when it announced itself as Googlebot, is no evidence about the real Googlebot, which crawls from Google’s own IP ranges and proves who it is by reverse DNS. What the challenge does shut out is everything that does not execute JavaScript: web archives, outside monitoring services, and AI assistants. So this page acts as the findable signpost: it explains, in the language people use, what the agency handles and what to have ready first, then sends the reader straight to the official site. ThaiGov.co is an independent directory with no affiliation to the NBTC; we take no complaints on anyone’s behalf and collect no personal data from readers.
How to use it
-
Go to your operator first — and get a case number
Contact your operator’s call centre, app or service shop, explain the problem once and completely, then ask for a case or reference number and note the date and time. That number is your proof that the operator was given its chance to fix things.
-
Gather the evidence before it disappears
Save recent bills, screenshots of messages and of the package you signed up for, speed tests with their timestamps, and every message the operator sent you. Operator systems keep only a limited history, so capturing it yourself early matters.
-
State plainly what outcome you want
Complaints move fastest when they name the remedy: a refund of what was charged without consent, cancellation and an end to the billing, or a corrected invoice. A narrative with no request attached is much harder to act on.
-
File with the NBTC through its official channels
When the operator will not act, answers something other than what you asked, or simply goes quiet, escalate — attaching the original case number and all your evidence. Check the official site for the intake channels and forms currently in use.
-
Keep the second reference number and follow up
Filing produces a second reference number, from the agency itself. Keep it beside the operator’s one and quote it every time you follow up, so you never have to retell the whole story from scratch.

Frequently asked questions
Do I have to complain to my operator first?
In practice, yes — the regulator works from the premise that the operator has already had its chance. Ask for a case number when you report the problem, because that is your evidence of having followed the order. If the operator does not fix it, answers beside the point, or goes silent, escalate with that number attached.
What falls outside the NBTC’s remit?
It regulates licence holders in telecommunications and broadcasting, so anything involving a mobile operator, an internet provider or a radio or TV station is in scope. Disputes with online sellers, with foreign social platforms, or a transfer scam are separate matters handled by other bodies. The dividing line that works in most cases: is the other party a licence holder?
I am being charged for a subscription I never ordered. What now?
Capture the evidence before it ages out: the charge lines on the bill or top-up history, the date the charges began, and any message the system sent you about the service. Then ask the operator to cancel it and refund what was taken without your consent, and get a case number. If you are told it is cancelled but the next cycle bills you again, keep that new bill as further evidence and escalate.
My number transfer keeps failing — why?
The usual causes are registration details that do not match what you submitted, an unpaid balance, or a contract commitment still attached to the number. Ask for the reason in writing or as a message, and fix that cause first. If you are refused repeatedly with no explanation, or the explanation does not match the facts, that is a complaint worth filing — attach every transfer-result message you received.
How do I find out how many SIMs are registered in my name?
Each operator has its own way to check which numbers sit under your ID number — through its app and at its service shops. Check operator by operator, because the picture is not pooled in one place. If you find a number you did not open, tell that operator immediately, ask for it to be cancelled and ask that the report be recorded, since a SIM in your name but in someone else’s hands can be misused without your knowing.
Someone called claiming to be from the NBTC, saying my number will be suspended. Is that real?
Treat it as a scam until proven otherwise. The standard script claims your number is linked to a criminal case, then transfers you to a second “officer” who wants personal details or money moved so it can be “verified”. Government bodies do not ask for OTP codes, do not ask you to transfer money to prove your innocence, and do not demand a decision within minutes. Hang up, and if you want to be certain, make contact yourself only through the details published on the official site.
How long does a complaint take?
It depends on the type of case and on how complete your evidence is, so there is no single figure that holds for every complaint. Read the timeframes and procedure published on the official site. What genuinely helps is keeping both reference numbers — the operator’s and the agency’s — and following up periodically while quoting them.
