Yes, EE told me that I have to make a call or send a text every 90 days to keep the number valid basically, that's fine, a £10 top up will last me years in that case. LOL

The intel I got on the railway communication system, the guy's worked on it for the past 16 years, he said that the network operators will still keep it open to users of old, basic mobiles for some time because it doesn't make financial sense not to, think of how many thousands if not millions of elderly people for example who still use them.
Having said that, most of the elderly took the experimental jab, if they all pass away within the next 2 to 5 years time, the financial aspect for them will no longer stand.
