Hoping someone can help me with this. Probably a total n00b question, but next week I'm going to the USA. I have my AT&T sim card ready to go. If I change my sim card from my present vodafone one, which is tied to my imessage, to my AT&T one, which hasn't been used yet - will I still get imessages sent to my vodafone number while I'm away or will they vanish into the abyss?

I've heard some horror stories, but personally never experienced an issue. Just make sure you reactivate iMessage again after you put the new SIM in.

Turn iMessage OFF prior to changing the SIM. Turn it ON when your new SIM is in.

Do the same when changing back to the original SIM. That should cover you.

as stated here, turning iMessage OFF apparently sends a 'msg' to Apple servers to deactivate their iMessage link to your phone/number, and this should 'unlink' the local number before you go.

with Vodafones $5-a-day deal, wouldn't it just be easier/cheaper to keep the vodafone sim in (unless you're making lots of 'overseas' US number calls?

I still want to be able to receive iMessages at my Vodafone number while I'm away, so don't want to deactivate that. Wish I had a plan that I was eligible for the $5/day a deal, but I'm on an old plan that still has eight months to run until the contract is over. But even 28 days, at $5/day, still works out cheaper to use an AT&T Sim.

You could always buy a cheap mobile when over there and turn off data roaming on your iPhone, relying on WiFi for iMessage.

turning imessage off WON'T stop texts coming, only "iMessages" from a non-sim device... maybe try turning off using imessage from the phone number itself?

my iMessages have the number greyed out from 'unticking', but if you are wanting to try it out before leaving, turn OFF iMessage remove the sim, and then turn it back ON... this should allow iMessages to your AppleID email/icloud email(s) but not the actual phone number, then the phone will get texts/calls from the AT&T and get iMessages from the regestered emails?
(vodafone numbered txt would wait until they timed out, so might need a sim-swap every couple days to 'collect' your VF sim txts too?)

Personally I think that the best set up for iMessage is to have it associated with your E-Mail address (primary iMessage account) as opposed to a phone number (secondary iMessage account/address). You can configure it to receive messages sent to either address on your iDevice, but choose a default account to send new messages from. That way if you change simcards you should be able to receive iMessages fine from your contacts (as your number may change but not your E-Mail address) - it also makes it easier if you want to iMessage off multiple Apple devices (now or in the future) such as off an iPad or Mac.

As for your current problem now though, the solution offered already should do the trick. :)

interestingly, although you CAN choose the default "send" address to NOT be the phone number, the receive address will always use the phone number to default... though as above, the actual iMessage account IS tied to your Apple account, so turning iMessage off +change sim and turn back on takes it with you to a new number as you want it to :)

If you've got a spare old iPhone lying around you can move your VF SIM into that, add it to your iCloud and activate before you go, and put your AT&T SIM in your regular one. It doesn't need a data connection, but now you have two mobile numbers linked to one Apple ID and iMessages to both will be delivered to both devices.
