USA roaming no signal

[Sam41]

I’m in the USA and my roaming isn’t working on my iPhone 12 Pro. I can’t get a signal. I’m in an area where there definitely is signal, but my phone doesn’t want to work. Data roaming is turned on, I have the international bolt on but still no luck. Don’t think it even registers emergency calls only as an option.

These are some tips to try :

•   Reboot phone.
•   Manually search for a different network
•   If using an iPhone, change data apn to  mobile.o2.co.uk
•   Call customer service to check for any roaming bars
•   Or if you message O2 using the social media links below, they should be able to help you with this

@Sam41 O2 throttle data speed in the US to 500kbps so you can't do much with your data except check email, if you can even do that.

It's in the Terms & Conditions you agreed to: O2 | Mobile Terms and Conditions - O2 Travel Terms and Conditions

There’s no fixed data allowance with O2 Travel, so to manage traffic (including audio and video streaming) we limit the service to 500kbps.
