An eSIM lets you activate a mobile connection without inserting a removable plastic SIM. For travellers, dual-number users and people who change phones carefully, it can be convenient. But an eSIM is not simply an app: your operator, phone model, regional variant and account all need to support it.
This current guide explains eSIM in Bangladesh, which operators publicly offer it, how to check compatibility and how to avoid common activation mistakes.
What is an eSIM?
An embedded SIM is a programmable chip built into a phone, tablet or watch. The operator supplies an activation profile, commonly through a QR code. Once installed, the profile performs the role of a physical SIM.
An eSIM does not automatically improve speed or coverage. Those depend on the operator, network congestion, location and plan. Its practical benefits are easier dual-SIM use, less dependence on a plastic card and quicker profile activation when the process is supported.
Which operators support eSIM in Bangladesh?
As checked on 21 August 2026, the following operators maintain official eSIM information or service pages:
| Operator | Official information | What to confirm |
|---|---|---|
| Grameenphone | Grameenphone eSIM page | Eligibility, supported device and current activation process |
| Robi | Robi SIM services | Current eSIM issue or replacement charge and service channel |
| Banglalink | Banglalink eSIM information | Eligible products, device list and registration steps |
Plans, fees and supported models can change. Robi’s public page showed Tk 200 for a prepaid SIM/eSIM and Tk 220 for SIM/eSIM replacement on the date checked, but always confirm the price at the point of service.
How to check whether your phone supports eSIM
- Find the exact model number and country or region variant under Settings > About.
- Search the manufacturer’s official specifications for that exact variant.
- On iPhone, look under Settings > Cellular or Mobile Data for an option to add an eSIM.
- On supported Android phones, search Settings for “SIM manager,” “Add eSIM” or “Download a SIM.”
- Confirm the model with the chosen Bangladeshi operator before paying.
A model family may support eSIM in one country and omit it in another. Imported devices and carrier-locked phones need extra care. Do not rely only on a retailer saying “global version.”
Before you activate
- Connect the phone to reliable Wi-Fi.
- Install pending operating-system updates.
- Back up important contacts and authentication codes.
- Keep your NID and the operator’s required registration documents ready.
- Do not photograph or share the activation QR code.
- If converting an existing number, keep the physical SIM until the operator confirms completion.
Typical eSIM setup process
- Request a new eSIM or conversion through the operator’s approved channel.
- Complete subscriber identity verification.
- Open the phone’s mobile or SIM settings and choose to add an eSIM.
- Scan the QR code supplied by the operator. Treat it like a password.
- Label the line, choose the default line for calls and data, and finish activation.
- Restart if requested, then test calls, SMS and mobile data.
The exact menus vary by manufacturer and software version. If the QR code reports that it has already been used, do not keep sharing or rescanning it on different phones; contact the operator.
Using eSIM for two numbers
Many compatible phones can keep a physical SIM and an eSIM active together, while some newer devices support multiple stored eSIM profiles. The number of profiles that can be active at once varies. Decide which line will handle mobile data and confirm how the phone handles calls arriving on the other line.
Dual-SIM convenience is especially useful for separating work and personal numbers. If you are setting up a small business, a memorable number can complement a professional website and email. SiteChai offers domain registration and web hosting for building that online identity.
Moving an eSIM to a new phone
Do not erase the old phone first. Some ecosystems support direct transfer, but operator approval or a replacement profile may still be required. Check the operator’s latest procedure, activate and test the line on the new phone, and only then remove the profile from the old one.
Troubleshooting
| Problem | What to try |
|---|---|
| No “Add eSIM” option | Confirm exact device variant, update the OS and check for a carrier lock. |
| QR code invalid | Use stable Wi-Fi, verify automatic date/time and ask the operator whether the code was already consumed. |
| Calls work but data does not | Confirm the eSIM is selected for mobile data and check APN settings with the operator. |
| Old phone lost | Contact the operator immediately to block or reissue the line and protect connected accounts. |
Frequently asked questions
Is eSIM faster than a physical SIM?
No. On the same operator and plan, the SIM format itself does not create faster mobile data.
Can I keep my existing number?
Operators may offer conversion of an eligible existing line. Confirm the current procedure and any replacement fee directly with them.
Can the same eSIM QR code be used on two phones?
Usually not. Activation profiles are sensitive and often single-use. Never post the QR code online.
Does every imported iPhone or Android phone support local eSIM?
No. Support depends on exact model, region, carrier lock and operator compatibility.
Bottom line
eSIM is useful when your exact device and operator support it. Verify the regional model, use only official activation channels, protect the QR code and test the line before deleting anything from the previous phone.
