Is anyone having this issue? I recently got a lg v20 sprint unlocked and the cellular signal drops constantly, it says "NO SERVICE every 3 seconds" then connects back to my mobile carrier.

anyone knows how to fix this? I know for sure it can't be a hardware problem because the phone is relatively new. :confused::confused:

That's a side effect of using a sprint phone on a different network. It all determines the carrier and area. Never buy a sprint phone with full intentions of it fully working on a different network. For me AT&T would do it. T-Mobile wouldn't.

Dude, this is so incorrect I've been using a domestic Verizon note 5 for the past 6 months on the gsm network by only changing the apn for data. Pretty much every flagship carries all the bands to reduce manufacturing costs it's just a matter of accessing them through the software.

Sprint locks it down software wise. Verizon does Not. So Verizon variant most wouldn’t have an issue. Even though with older phones like the S5 and G4 (only ones I’ve tested Verizon wise) service was unreliable in fringe areas as they would all the time go in and out of service, but only in fringe areas.

It depends. A lot of sprint models miss bands that Several GSM carriers use weather it be WCDMA or LTE


But generally 99% of people trying to use a Sprint device on a GSM network are gonna have an issue. While Verizon it’s probably less than have that will have an issue if even that.

I have a Sprint unlocked V20 and this phone was DSU (Domestic SIM Unlock) by Sprint to work on domestic GSM carriers and I tried using this with an AT&T card and it worked fine. Have you gone into Network settings and set the prper APN settings for your phone? Also are the bands supported in your area?

Umm...just flash the US996 Unlocked version of the Weta Rom....if you can or course (Bootloader unlocked) I have a Sprint V20, works perfect on T-mobile, and pretty much any SIM. It's not terribly hard to do, just dig through these forums for help.

Hello, I like what I'm reading but after trying to find what you are referring to I am at a loss. Can you please explain how you did what you did to get your V20 operable? Please......

I'm guessing your refering to the sprint model? It's unreliable unless your using it on sprint. It's not worth it honestly unless you got the phone for free.

Yes, it's a Sprint phone. I had it unlocked and the signal comes on weak...then goes away. I've tried everything to get it to be stable but at a loss. I did pay for the phone so it's quite irritating. :mad:

I value your opinion on other things but your information here is incorrect. I have successfully used a Sprint LG V20 unlocked by Sprint here locally on GSM networks as well as outside the US. It could be an issue with APN settings or selecting a proper network.
The Sprint V20 has enough band support for domestic GSM bands and I have first hand experience with it. It could be that the particular V20 could be faulty?

It’s not the band support that is the issue. And it’s not just the V20. In fringe/lower coverage areas it’s a pain to maintain a stable connection. I’ve seen this with both the G5 and V20. It makes it unusable. It also occurs on older Verizon devices as well like the S5 and G4 as an example.

It’s mostly a software issue that causes it. APN is data related and wouldn’t cause signal issues.


When I had a sprint G5 for my 2nd line, I go into city limits where coverage was good would almost work perfectly. Go home in a fringe area might as well pop the sim In a flip phone lol.

Fringe area is a very specific issue. LOL I cannot use my Sprint device on Sprint in Fringe areas. :)

That is true with Sprint coverage anywhere lol. (my local Walmart sells Boost mobile phones, even though we have ZERO sprint coverage) But in a fringe area on AT&T as an example the signal will drop in an out constantly. While any other phone will hold onto the signal perfectly fine and never drop and work perfect one 1-2 bars of signal.

I guess by fringe I mean a lower signal area not exactly fringe to the point of no service.

And there’s plenty of posts of Sprint G5 unlocked users that have the same problem.
