# How to activate an eSIM in Bulgaria (step by step)

> How to activate a Bulgaria eSIM: install the QR before departure, turn on Data Roaming, connect automatically.

Activating a Bulgaria eSIM takes a few minutes. Do it before departure so you connect on arrival.

## Before you leave

- Make sure your phone is eSIM-compatible and unlocked.
- Buy the Bulgaria plan at MerrSIM and get the QR code by email.
- Connect to WiFi and scan it: Settings → Mobile → Add eSIM.
- Label the eSIM “Bulgaria”.

## When you arrive in Bulgaria

- Set the eSIM as your data line and turn on Data Roaming for it.
- Keep your main number for calls/SMS.
- You connect automatically to the local network (A1, Yettel dhe Vivacom).

For a coastal holiday, a 10 GB plan covers maps, photos and video calls home.

## Does your phone support eSIM?

Before you buy, check two things. First, the phone must be eSIM-compatible: iPhone XR/XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and many recent Motorola, Huawei and Oppo models. Second, it must be carrier-unlocked. You can verify by dialling *#06# — if an EID number appears, your phone supports eSIM. This saves you any surprises when you arrive in Bulgaria.

## How much data you really need

For normal use — maps, messaging, social media and the odd video — budget about 300–700 MB a day. A light traveller is fine with 3–5 GB for a week, while anyone doing video calls, streaming or laptop hotspot will want 10–20 GB. In Bulgaria, download offline maps and use hotel WiFi for big downloads; that way a 10 GB plan comfortably lasts two weeks. If you run out, you buy a new plan in the app with no waiting.

## Common mistakes to avoid

Three mistakes often spoil the start of a trip. First: buying the eSIM at the last minute at the airport, when you have no WiFi to install it — do it at home. Second: forgetting to switch on data roaming for the eSIM line, which makes it look like it is not working. Third: leaving mobile data on your home SIM, which racks up roaming charges. Check these three and your connection in Bulgaria will be trouble-free.

## Coverage and 5G speed in Bulgaria

The eSIM connects to the main local operators, so you get the same coverage as a local, including 4G/LTE and 5G where available. In the cities and tourist areas of Bulgaria the signal is strong and stable; in very remote villages or mountains it can weaken, as with any operator. Hotspot is included, so you can share the connection with your laptop or a travel companion at no extra cost.

## Why travellers choose MerrSIM
