No service

No service since changing the number

[MI5]

Can you advise further please?
How/where did you change number?
Is this a new account, new phone, new network etc....?
If it's only recently changed it might need a few hours, maybe overnight to settle down.....

Also, check your postcode here http://status.o2.co.uk/

have you performed the sim swap if youve changed sim card sizes ?

Try turning your phone off and back on if you have.

It can tale from a few minutes up to 24 hours to properly settle.

I'm having the same issue, I got a new iphone today and recycled my old phone but have left the sim card in the old one. I'm not sure whether I need my old sim or whether this new one will be my same number. My phone has said no service since 5pm today

hi

You needed your old sim as part of the sim swap is to recieve a code on the old sim to start the swap on the new one.

Either ring 02 or use live chat or go into your local o2 store to get sorted out.

Contact us link with all relevant points of contact is at the foot of the forum page.

You need to report your old sim card as lost so it can be disconnected - You should never leave your sim in a phone (if it's active) when you recycle it.
If however, you did it in an O2 store and they have instigated the sim swap you will be OK - It will just take a while for the new sim to become active.
Keep turning the phone off and on or switch between airplane mode to help it along.

The store won't be able to help you as they send a text to the phone for security. You need to contact customer service as soon as possible to get the number transferred to the new sim card. Hopefully the old sim card won't have been used in the meantime.

They will however allow the OP to use the instore phone if they dont have another working mobile or landline.

Yes I hadn't thought of that, a trip into town to use the phone....

We have heard on quite a few recent threads on how difficult it is to speak to 02 right now via 202/4445 or Live Chat.

So Yes maybe a trip into town to get this sorted and services back up and running is warranted.
