suddenly my phone no. has disappeard
MichaelM_163088 Have you checked your Account Dashboard to see if it has your number and an active Smarty plan?
Next, how about a Network Startus check to see if there is a local mast issue?

Hi MSF thanks for responding - Yes, I've checked the Dashboard and it's got my phone number showing, and I've got 21MB left, enough for 1.5 day's use befor the next renewal which is tomorrow.
I've just run the Network Status checker, as you suggested. Got this: "We're working on the network in this area at the moment. We're sorry for any disruption this may be causing.We hope to be finished working on these improvements as soon as possible. We'll add any further updates here."
OK, bad news, but will that really cause my phone lose my phone number in the SIM manager - it says Unknown number" on the SIM manager?

Hello MichaelM_163088,
If you received a replacement SIM, the team may need to complete a manual switch of the ICCID number on the SIM (starting with 8944). Please chat with the support agents, who will look into this and see if this needs to be changed and whether it rectifies the unknown SIM error: https://smarty.co.uk/contact.

MichaelM_163088 Just wondering......if you ordered a replacement sim, then Smarty will have deactivated the existing one I think.
