[Q] [T-Mobile] VZW S5 Poor Performance on T-Mobile - Bad ROM?

[Taxmaster]

Hello All,

I have 2 Verizon Wireless Galaxy S5s running on T-Mobile, but the performance is awful.

• LTE is highly unstable
• Overall radio signal in the same place can go from 4 bars to 0
• Text messages don't send 1/2 the time, especially over Wi-Fi

Currently I'm running Rick'sRom V20 on 4.4.4 NK2.

I do not want to have to sell the S5 to buy a T-Mobile handset, as I have heard others having good experience taking other World-Devices from VZW to T-Mo without these sort of issues.

Is there anything I can do to improve this? Flash any newer ROM or radio?

Please let me know, thank you!

Wouldn't hurt to try different modems to see if one works better than the next. Here is an article on how to see what band your phones are operating on. My understanding is you need to be on band 4. I checked to see if this works on the galaxy s5 and it does. Mine is running on band 4.

How would you say your performance has been? Do you ever experience the phantom changes in signal strength like I had indicated above?

Never. I've been running different versions of RicksRom since back when we first got root and I was on NGC 4.4.2. Never any issues at all.
