New sim. Cannot send texts/sms. Old Samsung GT-E 1080i
Everything else seems to work. Noticed that only networks available on my phone seem to be T-Mobile, O2-UK, and Vodafone-UK. Phone shows connected network as T-Mobile. SMS message centre number is +447458399008. Tried altering this to T-Mobile's +447958879879 (is either of these number correct?), but phone won't accept any alteration. IMEI is [MOD EDIT: Removed], but your help web site says it doesn't recognise this number. I'm baffled and have run out of ideas. What can I do next, please?

24 August 2020 17:40hrs All seems to be OK now, including outgoing sms/texts. Thanks to somebody for sorting this out, but what a pain! Seems unlikely that these problems could not have been anticipated and prevented in the first place. No harm done, except I have even more grey hairs.
