S25 Ultra Sim issues?

[Mwalimu]

I have just received my S25 Ultra. After setting it up I find that it won't pick up the internet in public spaces. It works fine on WiFi where available.

Does it need a new SIM? My old SIM came from my my S23. Is this a 5G issue? Is it as simple as that?

I am having exactly the same issues. Areas i have been getting 5g for the past 12 months without fail, now i have a E signal at best. This issue has been for the last 72hours since i put my sim card in the S25 ultra

Same all my software and google playstore are up to date. Unless im connected to wifi best i can get is a E signal.
Can anyone help resolve this? I think i might return the phone to vodafone if i cant get it sorted by Monday

Hi guys i found a solution, i didnt realise vodafone had sent me a text message a few days ago telling me to click on link and update my APN settings as the network has identified i put my sim in a new phone. Almost recieved exact same time my data issues started 3 days ago. Clicked on the link today it took me to a voda website and asked me what phone i was using, typed in s25 ultra and it gave me some steps to carry out to update my APN settings, which are in the network menu. No problems since updating it. 5G, getting speeds about 150mbs a second on my mobile data. Hope this helps!!!
I apeciate not everyone is on vodafone in uk, it may help if you contact your carrier and ask them to send you some updated APN settings to support s25 ultra
