Swapping PAYG Micro SIM for nano SIM

[alecxm]

I have a Samsung Galaxy S3 with a PAYG micro SIM. I want to transfer my SIM to a Galaxy S7, but the SIM is the wrong size. How do I organise a swap to the smaller SIM size, retaining the number?

@alecxm Ask in your local O2 store. Please remember to bring your UK driving licence or passport with your for identification, otherwise they won’t be able to access your account.
Call Customer Services on 202 (Pay Monthly) or 4445 (Pay As You Go), free from your O2 phone.

Once you get a new sim you can complete the sim swap process online which involves taking your mobile number and both sim card numbers plus security question.

Hope this helps!

Check if you can push the middle out of your current sim first.

Is it not possible to order one online or by phone and have it delivered? Having to go to a store with a queue of people (which I tried to do today) seems very 20th century!

Not possible to push out centre - old phone, old SIM!

No. Its risky, there's too much fraud going on

Yes, you can call customer service to have one posted out to you.

Or advice from an O2 Guru regarding a way to get through:
If you call 4445, when it comes to the reason you are calling stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
Say "Upgrade", "Lost/Stolen" or "Fraud" if you have to, to get put through to someone.

Sorry was referring to ordering a new sim online. As I said you can phone them.

Sim swapping carries a big risk of fraud so when you go to an O2 store you're required to provide ID and ordering over the phone requires some security questions, stuff that only you would know
