Mobile data suddenly stopped working S23 Ultra

[Samkma]

This morning mobile data stopped working, no changes made, same network same location signal in full strength. Tried all normal procedures like on off restart check mobile data limit if set it's off. Twin sim on 3 network called three they reset my network and worked for an hour and back zero showing 4G but no data (only 40% of monthly allowance used) tried my daughter's Sky sim still same. Any help much appreciated. Connecting to wifi with no issues. I am out and about a lot.

Try resetting your Network Connection via Settings > General Management > Reset > Reset Network Settings @Samkma 

May I assume your sim card works as it should in another phone.

Run the diagnostic tool in your Samsung Members App too.

Hi, adding on to what you've already done & @BanOfBrothers as added, I know you said that your network provider reset your APN/network but just in case, double check it's correct with the link provided.

APN setting all looks good. The sky sim working fine it's three sim that has an issue.

I've also got a three sim & everything is working how it should, did you check if there's any network work being done in your area?

Hi, I just seen an email from three network, about upcoming work to their network system, hopefully this will fix your issue.

Or how long have you had your sim card they can give up on you after time I had mine 10 years lol so asked for a new worked like a charm.

[Samkma]

I am new to 3. Sim is less than 6 months old. My sky sim is 2 years.
