Can I use a Thai SIM in Myanmar?
A Thai SIM works in Myanmar only through international roaming, which you need to confirm with your operator. A local SIM involves registration, and a travel eSIM is the simpler alternative.
Quick answer
- A Thai SIM generally works in Myanmar only through international roaming, which requires your Thai operator to have a roaming agreement there and your plan to have roaming enabled. It is usually expensive and may be limited, so ask your operator before you travel. A travel eSIM installed before you fly is the simpler alternative.
- A local Myanmar SIM is the other option, but it generally requires registration with your passport, and the rules can change, so check the current requirements before you go.
- Our travel eSIMs are data-only, with no phone number and no calls or SMS, so they cover internet access rather than receiving calls on your Thai number.
Does a Thai SIM work in Myanmar?
Only through international roaming. A Thai SIM does not simply work in Myanmar the way it does at home.
Roaming needs two conditions at the same time. First, your Thai operator must have a roaming agreement with a network in Myanmar. Second, your plan or account must have roaming switched on. Some operators require you to activate it in advance, and some plans do not include roaming at all.
Is roaming in Myanmar expensive?
International roaming is usually more expensive than a travel SIM or eSIM, and it is sometimes charged per megabyte used or per day. Ask your operator about the rate and any spending cap before you switch it on.
If you leave roaming on and forget to restrict background data, apps updating in the background can use data without you noticing. Our guide on bill shock explains how to guard against this.
How do I check roaming with my Thai operator before I go?
Contact your operator through its customer service line or its own app, and ask the questions below.
- Does my operator have a roaming agreement in Myanmar, and with which networks?
- Can roaming be enabled on my plan, and do I need to activate it in advance?
- How are data, calls and SMS charged, and is there a spending cap or an alert when I go over?
- Do I need to change any phone settings, such as turning on data roaming or choosing a network manually?
If you decide to roam, turn it on using our data roaming setup help article.
Which SIM should I use in Myanmar?
It depends on what you need. There are three main routes: roaming on your Thai SIM, a local Myanmar SIM, or a travel eSIM.
| Option | Strength | Watch out for |
|---|---|---|
| Roaming on your Thai SIM | Keeps your usual number and needs no SIM swap | Needs a roaming agreement and roaming switched on; usually expensive and may be limited |
| Local Myanmar SIM | A domestic network SIM that can cover data and other services depending on the plan | Generally requires passport registration, rules can change, and you must buy it after you arrive |
| Travel eSIM | Can be installed before you fly, bought online, with no shop visit or SIM registration queue on arrival | Data-only with no number, calls or SMS, and your phone must support eSIM |

What if I still need calls and SMS on my Thai number?
Our eSIMs have no phone number and no calls or SMS, so they do not solve this directly. A common approach is to keep your Thai SIM in the phone as the primary line with its mobile data turned off, and use the eSIM for data. If you want to receive calls or SMS on the Thai SIM, you need to confirm voice and SMS roaming with your operator.
