Unlocked IPhone and changing providers/sim card

Bump123

Hi,

I have an iPhone 6 and want to change from 3 to the peoples network.

I purchased my iPhone unlocked via giffgaff and put in my 3 sim and everything has worked fine for the last 12 months.

Is there anything I need to do before changing my sim to the people's network? I've been reading a lot about iPhones locking to their first sim and provider.

Thanks

Put a sim for another network and see if you can get a signal, if you do then you don't need to do anything.

I don't have any spare nano sims for other networks

Giffgaff iPhones are unlocked, just put the new sim in and start using it. It's that simple.

Nope, just get your PAC from Three if you want to keep your number.

Three will be desperate to keep you though, and if you can be bothered they'll almost certainly match the TPO plan, but you'll get to keep Three's perks like Feel at Home.
