Payg sim not picking up 4g

[Andrew123Harris]

Hi all,

I’ve been with O2 for ages on pay monthly. We recently moved house and are waiting for broadband to be installed. I’ve been using my phone as hotspot but have almost used up all of my 25gb data allowance on my pay monthly sim. Maximum data bolt on was only 12gb and v expensive so instead I’ve got a payg o2 sim and topped up £30 for the big bundle of 125gb data. All topped up no problem. But with the o2 payg sim in I’m only picking up 3G. Switch back to pay monthly o2 sim and back in 4g. Any ideas? I’ve been through all the usual stuff on mobile data on my iPhone (iPhone SE) - turning on and off. Selecting 4g as preferred network…

Obviously not:

As they do say "PAYG SIMs ... you can enjoy our superfast 4G service."

Strange...

I'm sure a sim swap, as advised, will yield a result one way or another.

Thanks all for your help. The nearest O2 shop is quite a way away and I won’t have a chance to sort this before Tuesday when my broadband is installed and I no longer require the data. I don’t suppose you guys know if O2 will give a refund for the £30 because what I’ve been sent is useless for my needs. Or if they would transfer the data I’ve purchased to my pay monthly account?

You'd need to plead your case to customer services @Andrew123Harris

I don't rate your chances for that

But I hope customer service prove me wrong
