Bit of a technical post here
I've noticed that my Samsung A05s only accepts B3,20 and 28 4G, it has never showed B1.
My last Samsung A54 does receive B1 on 4G but then I realised that it has only ever showed B1 4G on 4G+ when CA with other bands.
Is it that 3 only allows B1 4G on 4G+ devices or is my phone (not 4G+ capable just basic 4G) faulty?
Also another off topic question for the moderators to answer: Is it true that 3 are/have switching off 3G-only masts off in areas without a 4G upgrade meaning that they have completely decommissioned those masts?
I have heard of those ones that had a recent 4G upgrade or just left switched on but also heard about 3 switching off some 3G-only sites forever with no plans to upgrade the coverage.
