How to replace a broken UK (O2) iPhone while in US?

[Humpty]

Hi,

I relocated to the US last year. Thanks for all the advice here re dual phones/two phones/sim swapping, etc.! I opted for the simple two-iPhone solution. I.e. A UK iPhone (O2) and a US iPhone (AT&T). 

MY UK iPhone is now dying, water damage. Is it possible to just get a secondhand iPhone and put the O2 simcard in and set up while i the US? I do use the UK phone in the US occasionally for certain tasks. 

I am anticipating issues with:

1) I'll need a specific iPhone for O2, which might have to come from the UK

2) There being no O2 signal(?) here it might not be possible at all

Can anyone advise what to do? Or might I have to wait until next trip to the UK. 

Thanks

Any unlocked GSM phone will happily take your sim card.

Just don't buy a CDMA device.

Assuming your SIM (UK one) is already active and you've used (as it looks to be the case) as MI5 has recommended put it into an unlocked GSM phone and it should connect to O2 automatically (or the roaming network in this case)

Hi @Humpty good to hear you got some useful information earlier to prepare for your relocation. Hope everything's been going well over there and you're keeping safe.  

It would be great to hear back from you to see if everything went ok with the new phone and your O2 SIM or if you need any further advice?
