F.A.Q

1. What is roaming and how does it work?

Anytime you go abroad and use your mobile phone you incur charges.

When you enter a new country your phone connects to the local phone network(s), this is called roaming. The new operator (visited network) will now handle the calls you make and receive. Rather than charging you for their services the new operator charges your home operator (your home network, e.g. O2, Orange UK , etc.) who passes this expense onto you on your next bill.
You could find yourself paying up to £2 a minute just to receive a call while you are abroad.


2. On what phone can I use this SIM card?

You can use the Bazar Traveller SIM on any mobile phone which is unlocked.
If you are unsure whether your phone is locked try inserting a SIM card from another network into your phone. If it works normally, your phone is unlocked and ready for your World Traveller  SIM card. If a message such as ‘SIM card restricted’ appears you will then need to unlock the phone.
