How do I know if my phone is locked?
Our service works with a vast majority of mobile phones but you must make sure that your mobile phone is unlocked.

You can check if your phone is unlocked by inserting another SIM from a different network provider in your phone.

When you put the SIM into your phone and you get one of the following messages, your phone is probably locked:

"Insert SIM"
"Enter subsidy code"
"Phone restricted"
"SIM not valid"
"SIM not accepted"
"SIM locked"
"Wrong SIM"
"Network locked"

If your phone is unlocked, your phone will display the name of a mobile network, e.g. Vodafone.

Phone unlocking

If your phone is locked it’s easy to unlock it online or at a local mobile phone shop.

Are my contacts stored on the phone or on the SIM?
Check if your contact numbers are saved on your phone by inserting your SIM4travel SIM. If you can see your contacts, your phone is ready for use.

If your contact numbers are not available, then place your UK SIM back into the phone and copy your contacts from that SIM onto the phone.

Your contacts

We recommend that you update your numbers to include 0044 so you can call back to the UK. Make sure you take off the first 0 on the UK number then add 0044 e.g. 0208 999 123456 would become 0044 208 999 123456.
