registering classic sim for data use only in a tp link router

[Schooee]

Hi, I've a Classic sim card for use in a TP link router to access Wifi whilst away in a motorhome. I have a mobile with another provider. I used to be with O2 years ago and had an account which was closed.

I tried to register the new sim card on line a few days ago in what I thought was  by opening a new account and somehow O2 threw up my old closed account. I can't seem to register the new sim card on line as I can't get the security code because they think it's going to be used in my mobile phone which it isn't.

Can  I register the new sim purely on line, and if so can I then alter the payment frequency from a monthly tariff to one where I can top it up when the credit is used as I won't be using mega amounts of data. 

Thanks,Phil S.

No to everything unfortunately.

You can't get a data only PAYG sim anymore from O2 and phone sim cards cannot be used in routers.

You can hotspot from a phone, but that's all.

To register any sim you'll either need to contact O2 to add it to your current account or use a different email address.
