How to check your prepaid mobile balance in Romania: a quick USSD guide for UK travellers

If you're a UK visitor using a Vodafone Romania SIM, dial *100# to see your balance instantly. The code works without data or Wi-Fi, and a pop-up message appears within seconds showing your remaining credit in Romanian lei. Alternatively, the MyVodafone app gives a fuller breakdown of data, minutes, and SMS allowances, though it requires an internet connection.

This guide is written for UK travellers who have picked up a local Vodafone Romania SIM or are roaming on a Vodafone contract. The steps below apply to prepaid SIMs bought in Romania and work on both Android and iPhone devices.

Checking your balance with a USSD code

USSD codes are short dial strings that trigger an instant response from the network. They're free to use and don't consume any of your data allowance.

1. Open your phone's dialler (the same screen you use to make calls).
2. Type *100# exactly as shown, including the hash symbol at the end.
3. Press the call button.
4. A pop-up message will appear on screen within a few seconds. It shows your current balance in Romanian lei (RON).
5. Tap OK or dismiss the message once you've noted the figure.

On iPhone, the pop-up appears automatically after you press call. On Android, it usually shows as a system dialogue box. If *100# returns an error or no response, dial *134# instead; it performs the same function and serves as a backup option. Both codes are confirmed valid for Vodafone Romania as of May 2026, according to romaniaesim.com.

What the balance message tells you

The response typically shows your remaining credit in lei. If you're on a prepaid plan, this is the cash balance available for calls, texts, or data top-ups. Postpaid customers may see a summary of remaining allowances instead.

If the message appears in Romanian and you're unfamiliar with the language, "lei" refers to the currency and "valabil până la" means "valid until". The figure displayed is usually straightforward: a number followed by "lei" or "RON".

Using the MyVodafone app for a detailed breakdown

The app offers more information than a USSD code. You can see remaining data, minutes, SMS allowance, and your credit balance all on one screen.

1. Download the MyVodafone app from the App Store or Google Play if you haven't already.
2. Log in with your Vodafone Romania account credentials. First-time users will need to register using their phone number.
3. Your balance appears on the home screen once you're logged in.
4. Tap through to "Contul meu" (My Account) for a fuller breakdown of data and call allowances.

The app requires a data or Wi-Fi connection. If you've run out of data entirely, a USSD code is the safer first step.

Troubleshooting USSD codes that won’t work

A few things can block USSD codes. Check these in order:

• Make sure you're dialling from the Vodafone Romania SIM, not a second SIM in a dual-SIM phone.
• Check your signal strength. USSD needs at least a basic 2G connection to process.
• Try the alternative code: if *100# fails, dial *134#.
• Restart your phone and try again. Some devices cache a failed USSD session and won't retry until rebooted.

If neither code works after a restart, the MyVodafone app over Wi-Fi is your next option. You can also call Vodafone Romania customer care, though be aware that support may be in Romanian unless you request English-speaking assistance.

Does this work while roaming outside Romania?

If you bought a Vodafone Romania SIM as a visitor, *100# and *134# should work while you're in Romania with a signal. Roaming outside Romania may block USSD codes depending on the visited network's compatibility. In that case, the MyVodafone app over Wi-Fi is the most reliable way to check your remaining balance.

UK Vodafone customers roaming in Romania on a UK contract should use the standard UK balance-check methods (*#1345# or the UK MyVodafone app) rather than the Romanian codes listed here. The Romanian USSD codes are specific to local Vodafone Romania SIMs.

When to contact Vodafone Romania directly

If you're unable to check your balance through any of the methods above, or if the balance figure looks incorrect, contact Vodafone Romania customer care. The main customer service number is 222 from a Vodafone Romania SIM, or +40 722 222 222 from any other phone. Support is available in Romanian and English, though you may need to request an English-speaking agent when the call connects.

For UK Vodafone customers with queries about roaming charges or international usage, call 191 from your UK Vodafone number or +44 7836 191 191 from abroad. The UK team can clarify roaming rates and help with billing questions related to your UK account.
