Bad Signal

"Solution edit: received better connection through: turn phone off. take sim out. turn phone on. turn phone off. put sim in. turn phone on. seemed to refresh it's band or blocks at tower side. symptom was only call sending party had clear voice connection. receiver was very low latency. purpose was (assumed) faulty tdma frequency block allocation."

 

Here's my "chat" submittal:

George Murphy
Calls are breaking up. Even with Ting support number outside on my LG-H700 using T-mobile GSM.

This is unacceptable. Right when I need the service everything goes to shite. Phone shows 4 bars latency with GSM antenna and yet it doesn't carry.

  • Hey George --

    I just spoke to Muki. He confirmed that the chat software kicked him out of your chat and by the time he was able to get it back open (our software can be fickle) it couldn't find the open chat. 

    If you try again, we should be able to help you!

  • Looks like a major local problem with T-mobile unless my phone is at fault.

    actually nationwide: https://downdetector.com/status/t-mobile/map/

  • I jumped into the ticket, and if the IMEI you provided in your latest request is the one for the LG-H700, then your issue is that the phone doesn't support VoLTE on T-Mobile. That's a problem we laid out here on Reddit last year.

    It supports LTE Band 12, and VoLTE on AT&T, but not VoLTE on T-Mobile. Your call quality and reliability issues are probably going to get worse on any T-Mobile MVNO (Ting GSM included) with that phone as laid out above.

    So, in terms of "blame", it's a weird combination of your phone and what the network expects. We've been working on trying to get this visibility to customers prior to the signup stage, but some things move slower than others when (again as laid out in the above link), 2G talk and text still works for many people on the network.

  • What if I flash it with android and lg's stock firmware? removing at&t malware. I plan on doing that this winter anyway

  • You can try to flash the stock firmware, but two things on that.

    1. There's no warranty on that, as that's basically a custom ROM. We can't be held responsible for that and cannot encourage it, though we do not actively discourage you from doing what you'd like with your hardware. 

    2. The VoLTE flag is on the network side. T-Mobile looks at the IMEI and determines there if it's VoLTE compatible. Similar to Sprint's device database, I'm not sure anything you do to the phone itself will affect how the network treats its connectivity to the phone. 

    If you do decide to try it, we can pinpoint any calls you make to see if they went over VoLTE or the standard 2G/3G connection you're struggling with right now. Though, you can also keep track of this by checking if the LTE symbol disappears while you're in a call and reappears after the call (2G/3G calling) , or if it stays put the entire time (VoLTE calling).

  • >The VoLTE flag is on the network side

    and the fcc looks the other way.

    received better connection through: turn phone off. take sim out. turn phone on. turn phone off. put sim in. turn phone on. seemed to refresh it's band or blocks at tower side. symptom was only call sending party had clear voice connection. receiver was very low latency. purpose was (assumed) faulty tdma frequency block allocation.

    certainly not a permanent fix. i only want this phone to last until next summer. will attempt compiling and flashing it's firmware when i have a backup voice connection (maybe). i bet europeans and chinese don't have to put up with this locked hardware crap that we have.

  • You're not wrong that it's remarkably frustrating that we don't have the telecom standards of many developed western nations, but that's how we've decided to govern. 

    It's likely your voice call quality issues will come back, though. As noted in that link I provided earlier, the problems can ebb and flow which is why it's remarkably difficult to pinpoint for any CS rep of any company. You just happened here to get the ear of a company that knows the nuts and bolts of it. 

    If at all possible, look at an inexpensive VoLTE phone that is unlocked with all carriers to carry as your primary voice handset. You can then use the H700 as a data-only device either over Wifi, hotspotted to the VoLTE handset or as a standalone Ting line.

    I actually do a variant of this, but I carry multiple phones for a reason. The inexpensive VoLTE multi-carrier phone I chose was the iPhone SE. It's <$100 used on Swappa, is VoLTE on all 4 networks and doesn't take up much room in your everyday carry.

    That's not a perfect solution, but it's one I've been suggesting lately to the many MANY T-Mobile MVNO (Mint, Ting GSM, Fi) customers with this issue and no desire to drop a cool few hundred on a new phone when the one they've got technically works fine just not as great as it should.

  • iPhone SE is what my brother uses through T-mobile. Pains me to realize that a tech no-nothing chose better hardware than me. I went with H700 because it's ruggedized. Android is total bunk especially any carrier locked system. Linux smartphones are all broken excepting EU certified hardware on European networks. My experience tells me to go with a MediaTek feature phone like the Alcatel for voice only on Sprint (or hopefully Verizon soon). Leave TCP/IP where it belongs on a secure modem and router.

    An update summary is that I believe my signal was hopping near Washington D.C. and lost during this impeachment circus. After resetting which ridiculously requires sim swapping it put me on a more northerly antenna/tower traffic route.

  • There are some nice feature phones out there, but you'll still want to make sure they're VoLTE for the network you'll use them on, as not all are.

    That's another reason I suggested the SE. Its small size makes it comparable to a feature phone but is guaranteed VoLTE compatibility and software for at least one more go-round by my count on Apple software updates.
