Change "My Number" iPhone 4S

Thank u so much! I was looking for that phone but I tried once again activating FaceTime and it worked well just like described on this post!! You were really helpful guys thanks a lot!!

This solved my question thanks a lot!!

I think this mismatch has been screwing up my iMessage and FaceTime activation. My 4S has been sending the activation texts about 3 times per day since iOS 5.1 update and it's racked up a cost of £10 over the last month. My mobile plan doesn't include texts so I pay 10p for each one.😠

Just got my new micro sim - fingers crossed it stops the texts

Silly question, but I'm still gonna ask anyway..

What do you mean by editing the number in another phone? How?

I used a 3GS on Three

Put the sim card in

Go to settings>phone>my number, tap the arrow next to the number. Change it to your ported number

Pop it back in your 4s and iMessage is sorted

This worked for me:

Turn off iMessage / FaceTime.

Take out the SIM and restore in iTunes without SIM (back up first obviously).

Put SIM back in and turn on iMessage / FaceTime.

Good luck.

Changing the micro sim and resetting 'My Number' has finally stopped my 4s sending iMessage activation texts all the time.

We'll see if I get my money back from Three for all those silent texts. I've put in a claim and have a case number

phenline, i have the same problem. and i went onto that link you posted, but i dont know what to do. i tried calling that number, but it doesnt do anything..... help ???

Phenline,

The other posts were garbage ;-) Your link was the only answer that lead to an actual and complete solution. Granted, this will only solve the issue for those on the Sprint network, but I would assume that all networks have a similar key code entry for a "service update" procedure. Thank you.

For those on the Sprint Network:

on your Sprint iPhone 4 or 4S key pad, dial

##873283# and hit [call]

Hit [OK] in answer to the "Starting Service Update" pop-up window.

Wait for the “Service Update Complete” pop-up and hit [OK].

Reboot your Sprint iPhone 4 or 4S.

Done!

Problem solved.... all number discrepancies will have been corrected.

Thank you for you posts... everyone.

I've had the same issue with an iPhone 4S, moving from O2 to Three. I brought my number across, yet the phone / iTunes still displays the temporary number that came with the new SIM.

Tried the above - seemed to work for iMessage and FaceTime. However, iTunes / Phone app still displays the old number.

I rang Three, and I was told it was a known issue which was being worked on, and that the solution was to be issued with a new Sim (which they offered to post at no cost). Instead I collected one from my Three store (also at no cost).

He also pointed out the following risk with this issue: There is a small risk of sending the old number when sending an SMS (confusing for the recipient).

These are the most disconcerting kind of errors - intermittent.

Waiting for my new sim to activate - fingers crossed.

Hi

Same issue on iphone 4s moving a number from O2 to Three.

Basically if the above doesn't work, you're probably running the latest iOS update (5.1). Which means the only full solution (to fix the phone number as well as imessage and facetime) is to get a new sim from Three - either by ordering one in or going to your nearest store. I'd recommend the store option as it is far quicker and once a new sim is ordered you might be left without service until it reaches you.

Apparently apple are working on it so by the time iOS 5.2 is released this hopefully will no longer be an issue...

Thanks!! Worked great moving from Virgin (who don't offer iPhone in UK yet - wonder how many customers they're losing through that!) to T-Mobile.

This was really bugging me as I (wrongly) assumed that this would automatically change when the number flipped over to my T-Mobile acccount/sim. Thanks - you're a star!!

You are a life saver! @ Dusty D . Sorted now. Cheers :)

Excellent!! Works a treat on the iPhone 5 too!! Cheers

This also worked on my new iPhone 5 (although I'm still struggling with the facetime bit, but I assume it will eventually work)
