Upgrade pay as you go phone and sim

[Peppermint]

I'm in the United States. I would like to upgrade my very old phone with standard sim card. How can I upgrade? How can I use my old number? Will they deliver it in my US address? If I authorise a friend to pick up for me what do we need? Please advice. Many thanks!

Hi @Peppermint. 

Easiest way to upgrade is through your MyO2. 

You will get a new SIM with the phone which you can use to perform a SIM swop to retain your number https://swapmysim.o2.co.uk/ 

Your problem will be delivery or collection. They won't post to USA so you'll need a UK address or if delivered to store, your nominated friend will need your ID to collect it.

Best option is to call customer service. They sum only deliver however to the UK address on file. You need the Classic 3.2.1.sim if you are in the US unless you want to keep the same number and tariff  Use the online store to transfer both

Thank you! How about if I buy a phone here in the US? Will my standard sim card will still work?

As long as that phone is unlocked  yes

@Peppermint you will need to ensure you buy a GSM phone and your SIM will work ok providing the phone can be unlocked from the network. CDMA phones won't work with an O2 SIM card though.
