- Whenever you go abroad it's a good idea to top-up your mobile before you leave.
If you need to top-up from overseas you have a number of easy options:
- You can take an O2 voucher with you
- Use your credit/debit card
- Top-up online through our website
We suggest using your credit/debit card as this is the most user friendly way of topping up whilst abroad - simply call the O2 Top-up line.
Calling the O2 Top Up line
If you're in a direct dial country, call the O2 Top-up line FREE by dialing 4444 or by using Hotkey 3 or on your Pay & Go mobile. Alternatively, dial +441753 552277 from any phone.
If you want to top up from a country that doesn't allow direct dial please enter *111*# then press the call button. Your mobile phone will go on standby for a few seconds before it rings. Answer the call and simply follow the voice prompts to access the Top-Up line by dialling 4444# and then proceed through the top-up service as you would in the UK.
