# How much data do you need for Romania?

> How much data for Romania: 5 GB a week, 10 GB two weeks. MerrSIM plans from €1.29.

Before buying a Romania eSIM, work out how many GB you need. It depends on your days and what you do online. On the Transfăgărășan in summer, the switchbacks make epic Instagram videos — with an eSIM you post from the top.

## How much data you need

- Light use (maps, WhatsApp): ~300 MB/day
- Moderate use (social, photos): ~700 MB/day
- Heavy use (video, hotspot): 1–2 GB/day

Multiply by your days and add a little buffer.

## The right MerrSIM plan

## 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 Romania.

## 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 Romania will be trouble-free.

## 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 Romania, 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.

## Activation in a few minutes

Do the install before departure, while on WiFi. Open your phone settings, choose to add an eSIM and scan the QR code you received by email. Label the profile “Romania” so it is easy to spot. When you land, set the eSIM as your data line and switch on data roaming for it — that is normal for travel eSIMs and adds no fees, because the plan is prepaid. Within seconds you are online, with no need to hunt for public WiFi.

## Coverage and 5G speed in Romania

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 Romania 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.

## FAQ

### Does the eSIM work in the Carpathians?
In towns and main roads yes; on remote peaks signal may weaken.

### Which eSIM is best for Romania?
MerrSIM offers the best value: from €1.29, local 4G/5G, hotspot and EUR billing.
