Thanks so much for the info! Life is a forever learning process and I love it!
With the Three (and thus basically, Smarty as they are the same company) simcard in my S7, I started looking at the info on 'Network Cell Info Lite' - the phone was mainly connected to band 3 and speeds were so-so, despite it saying 4G+
I then noticed it switched to band 1 and I tried speedtest - BOOM 60Mbps!
So, now with the Smarty card in my B525, I'm hoping I can get Band 1 - is that possible?
A previous poster said that with various 'inspecteur' programs (I'm currently using huactrl on Android), you can force it to only receive on certain bands, so I'm thinking if I can only use 3 and 1, I can get good speeds?
The B525 HAS shown 4G+ before, so I'm guessing it CAN work.
I didn't know if it could do CA and now I know it can, and secondly that it can only do 2 bands - so thanks
I hear what you're saying about the internal antennae - I've tried a couple of external options and internal is by far better - crazy. I guess it'll only get better if you use one of those expensive Poynting things.
I've found a good posi for my B525 and am currently getting -4db on RSRP and -81db on RSRQ...but no 4G+
As you said, lots of variable involved, but I shall persist!
