I'm currently using an iPhone 4 that is locked to Virgin Mobile. However, September onwards I'm going to be working and living in France for a year.
If my phone is locked to Virgin, does that mean my phone would work with a sim card from Virgin in France?
Welcome to the community and thanks for posting.
We only supplied from iPhone 4s and upwards. At present the handset is locked on to a UK carrier network so it's likely it won't work with a foreign SIM card.
If you unlock it then there's a possibility the handset will still only be locked to UK carriers only. You'd have to take it out there and test it.
I hope this information helps. Please let me know if you have any further questions.
