S21 + Poor Vodafone Signal Strength

[The_Sentinel]

I have recently purchased a refurbished S21 + phone to replace my previous S8+ phone that finally gave up the ghost.

The Vodafone signal on the S21+ is very poor or mostly non existent, compared to what I was getting with the S8+. Initially I used the old SIM from the S8+, but due to the poor signal strength on the S21+ I contacted Vodafone and went through a series of checks and tests. There was no improvement after these checks and Vodafone suggested I got a new SIM,  considering considering my existing one was around 10 years old.

I got a replacement SIM, but there was absolutely no improvement in signal strength with the S21+.  Can anyone suggest what the problem might be here? As you can imagine, its scary leaving home and driving around with a phone that hardly ever connects to the Vodafone network. 

Thanks in advance...…K

Hi, I'm glad Amazon came through for you and that you managed to get hold of a handset that finally works. To be fair, even I wasn't aware of the bad rep regarding the S21 modem.

Hi, thanks for that info.
I've returned the S21+ to Amazon for a refund. It had absolutely appaling connectivity issues and just struggled to latch on to a network. Even when it did, it would drop off the network and stay disconnected 95% of the time.
I"ve bought a refurbished S20+ now and so far had no problems with it at all. I preferred the more robust feel of the S21+, but not to worry. At least I have a phone I can use now.
Thanks again. How can I mark your post as a Solution?
