Nokia 800 Tough Roaming Not Working Properly

[otronics]

I have a Nokia 800 Tough purchased in the UK and an O2 Nano SIM.

My plan is Classic Pay and Go.

I am currently in Portugal and roaming isn't working properly.

It is connected to a network (MEO) and has full signal. Next to the signal bar is a 'r' to indicate roaming.

I cannot use data, send or receive calls or text messages.

I did receive a text from MEO saying "welcome to Portugal etc" but that's it.

Interestingly, I did receive a notification saying I have a voicemail but I can't call 901 to retrieve it.

Things I have tried/checked:

• APN settings are the O2 default.
• Data setting is on as is data roaming.
• I have turned off 4G (phone doesn't have 5G).
• Phone has been rebooted many times.
• I have tried manually connecting to other networks but there are none in range.

Any ideas?

Thanks.

Oliver.

APN Settings for PAYG are what you have set, right?

Leave 4G on.

Ensure Data Roaming is set, as well as roaming, @otronics
