Help with roaming and calling abroad
Answers to some of the more common questions about roaming abroad.
We have different world zones to simplify overseas call and data charges – which means you don't have to remember call costs for each individual country.
The world zones differ slightly depending on what type of contract you're on and which Bolt On you’re using – see world zones here.
It's always free to receive a text on O2 Business when you’re overseas.
Calls cost more abroad because O2 Business has to pay for customers to use international networks, which is above and beyond your usual tariff payments.
Voicemail is generally set up to divert calls when you're on the phone, out of range, or when your handset is switched off. In the UK these diverts are free of charge, but if you don’t answer a call when you're abroad, the foreign network sets up another call to the UK.
This is the additional call. We're working to solve this issue, however if you're concerned about this, we would strongly recommend setting up 'divert all' for calls to voicemail so you’re not charged. To do this while you’re overseas, you can use Voicemail 901.
Voicemail 901 lets you hear your messages overseas.
To set it up:
All calls made abroad are shown on your bill under Roamed calls, and include the network you called from.
We try to show overseas call charges on your next bill, but sometimes there may be a delay.
We're just checking to see if there's an available agent.
