I'm in the UK and have an s-off Sprint M9 running Bad Boyz Nougat ROM. Works great but I'm not sure if my data is running at 4g as the status bar cell signal only ever shows a small "g". In the APNs the bearer is stuck at unspecified...LTE is a checkbox option but it reverts to unspecified. I'm...

A member of my family has a GS9 under AT&T, and they decided to buy a Straight Talk SIM under Verizon's networks, but AT&T is GSM and VZW is a CDMA network! I am worried that it won't work, so can someone tell me if it would even REMOTELY work. I don't want to switch any CSC files, as they...

Just got a pristine Note 5, got it rooted and twrp' d. I'd love to have it unlocked for rom purposes. I do own the phone outright so I'd imagine I could call Sprint for the code but XDA is where my heart is so I wanted to ask here first. Any remote unlockers available? If this is frowned upon...

Hi everyone, This is a new thread which is a follow-on to my "? How to get LTE speed on US LTE tablet running ROW LTE Image?" thread. Basically, since many people said it was OK to run the ROW LTE image on a US LTE original Shield, I flashed the 5.0 Nougat image onto my shield (using the 5.0...

I was checking XT1103 i.e. NEXUS 6 64GB in USA. ITs now available for < 250$, which I think is quite a fantastic price. I do not really need "latest and greatest" so older gen phones are ok. However, I am wondering if the XT1103 works in India with 4G-LTE ? From the wikipedia it says 3g - 1 / 2...

Recently ended up with this phone, wanted to use it on straight talk with a AT&T sim since it is unlocked. It works, kind of. I get one bar or no signal in places I have 2 or 3 bars on my old HTC one M8. I thought about trying a different rom or a different radio if you can flash those on...

Bought this device 3 week ago. Went for a train ride over a route that I used to use my Sony Xperia Z2. Using the same sim, I noticed the T815 LTE was constantly losing its signal both data (H+ etc) and GSM. I gave it a few week, just in case EE (TPO) was playing games with its signals and...

Alright, after hours on the phone and resolving nothing with ting to fix my mms issues, I found a fix myself. Months later. They were thinking the Sim they sent me was "faulty" but was not as a family member has the same phone on ting with the same problem. First to elaborate those who...

I know this has been probably asked a thousand times before, and I've thought I knew it myself. "Unlocked" nexus means I can basically put any SIM card in it and it'll work regardless of where I bought it. But, why is there a US version and an international version? What are the differences then?

Are there any Android phones released in 2015 that are capable of working on both GSM and CDMA networks? Thanks in Advance for the answers

Hey all, I recently picked up a Note 5 for the Wisconsin carrier Cellcom as their network is great up here. However, unlike pretty much every Note 5 I've seen (including the US Cellular Note 5 which has the same model number), the option to put the phone in "global" mode is missing. I popped an...

Hey guys, ive just bought one of these and its on 4.4.2. Its not giving me a notification for the lollipop OTA, but the HTC sync software says there is one. Now my question is, Should I root and unlock bootloader before doing the update or after? Which one would be a less time consuming process...

Hi all, I got my sprint Moto E a few weeks ago. Its working international, but the problem is that its locked to 2G only. I think its the radio that is locked. I had a smilar issue with my HTC one E8 sprint when it was updated to Lollipop where the #G part of the radio was disabled. I used this...

Hi, I have owned this device (S2 Skyrocket i727) for 3 years now. It is still an incredible phone for daily usage. One thing that has bothered me is the difficulty in changing network mode in the stock AT&T ROM. One elaborate way to do that is dial *#*#4636#*#* and choose the network mode. But...

I've got an unlocked LGLS991 and wanted to edit the APN settings for GSM use. It looks like there is no option to edit the network settings under the network menu and the ##3282# menu only allows me to view APN settings, not add or edit. Do I need to poke around in hidden menus? Or is there...
