Buying a new samsung s21 from samsung store

[Kyle5]

If I buy a phone from samsung website with the intention to pay monthly. Can I transfer my current sim only contract over to the new phone. Bare in mind I did not purchase this phone from 02

[jonsie]

Yes of course @Kyle5 

You can use your sim in any phone

Bear in mind that if you are in a 5G area then you will have to have a new sim

For that

You'll need to call O2.

Numbers here

Advice from an O2 Guru regarding a way to get through:

If you call 202, 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 an advisor.

Press Upgrade, Lost/Stolen or Fraud if you have to.

You will need to call O2 to migrate your current sim only number to your new contract.

Unless you have reached your minimum term, they may be cancellation fees to pay.
