[Moto G4 with Amazon ads] Always losses carrier network after 24 hours

[Zadornov]

Hello everyone,

I just bought a Moto G4 16 GB with Amazon Ads for my wife, but we are facing a very annoying problem: the carrier signal always dies after 24 hours give or take. We tested with a different SIM card and the same thing happened. When this happens the device only shows "Emergency Calls Only" and we have to reboot the phone in order to get the signal back.

So, is anyone else facing this problem? Is this really a problem with this phone in particular or every moto g4 has this problem? Should I return the device to amazon?

Thank you very much for any information you can give me!

No problems here since I got my phone last week and I have T-Mobile. You might have to check your apn settings with your carrier.

I tested the SIM card in a different phone and it worked flawlessly (I also use T-Mobile). The strange thing is that the phone gets the signal very well during more or less one day, after that I have to reboot to get signal again.

Well, this is probably a problem in the device. I already asked Amazon to send a replacement.

Try my APN settings to see if it helps, but locations very important

I also have the cellular data always active checked off

Thank you, but I just use the t-mobile network. In fact, my carrier is called campusSIMs and it is a MVNO that uses t-mobile network. So, my APN configs are a bit different from yours.

However, I didn't know about this mobile data thing. I didn't touch the developer options. Maybe, it can be a good idea.

Thank you!

It won't be your APN settings since that controls your data settings. If the sim is ok then it could be your phone.

I'm seeing a similar problem with the data portion of the network (also on T-Mobile). While I'm able to send and receive calls and texts, data doesn't work. There's no indication that it's attached to LTE or even 3G (just a standard signal bar with no other information). I moved the SIM card back to the old phone it was in and it works fine.

Things actually worked yesterday, so something happened overnight to break it.

That could possible be the APN settings. Although usually it's the opposite, they don't work at first then they update from the network later on. Most times the APN settings will set themselves but on the odd occasion they need to manually edited. I don't use T-Mobile but the APN settings are easy enough to find.

Sounds like you need to manually enter the APN settings. What you describe is exactly what happens when it hasn't loaded an APN.

I'm "kinda" having an issue here. It's a little different though; the phone works ok for a while (for me about 3 hours, usually), and then I still get an LTE indicator, but have no network connection (get errors in apps/"No internet" page in chrome).

Other times, I lose LTE and get locked in 3g (H indicator), and can only get LTE back by going to Settings/More/Cellular Networks/ and toggle preferred network mode to 2g or 3g, let it connect (H or E), then toggle back to LTE.
Motorola responded to a bad Amazon review requesting I post asking for help on their forums.

I'm active over on their forums also and it's good to post over there in case you ever want to do a soak test. They look at your posts there when they ask for soak testers. As for your problem, I've seen it shift back and forth if you are in an area between towers and one isn't sending out LTE. If it were that I wouldn't think you'd get it back so easily. There's an app, don't remember the name, that will show the towers and signal relative to your location, If might be interesting to look at that.

Having the same issue with radio. Just replied to your post, Kalash.

Ok, we got a new phone from Amazon and it has the same problem. So, I believe this phone does not work very well with MVNOs.

I notice that the problem is that the phone cannot reconnect to the network after losing the signal. For example, if you go to an area with bad signal and, eventually the signal vanishes, the phone will not be able to reconnect to the carrier network. The phone only reconnects after reboot. Airplane mode does not solve the problem.

This does not happen with my Blu Life One X. So, I think it is a software problem.

That's not true on all mvnos' apparently. My wife's phone is on Consumer Cellular, an AT&T mvno and it's never done that. We've been in a no service area several times and it's always connected immediately when getting service back.
