I have a unlocked Samsung galaxy on5 from MetroPCS (USA).
It is sim locked and work/tested on various other service provider.
But when its used with Reliance JIO in India it is not working though it shows 4G LTE but the VOLTE feature doesnt work and due to that calls are only possible through the app not the native dialer. any possible solutions?

I use SGS5 (SM G900F) LTE model and I have subscribed to 4G services on Airtel network in India. The issue is that the handset does not latch on to the 4g network. its been a task following up with the service centres for a solution but in vain. I still have not been able to find a solution after 3 months. Can anybody help me with a solution.
Thanks in advance

I bought an S7 Edge SM-G9350 Dual Sim that is unlocked. I was planning on using it on AT&T but apparently the Dual Sim model isn't compatible with the 4G LTE in the US. The AT&T rep I worked with called his Samsung rep and verified it wouldn't work on 4G. We checked all the APN settings and bands the device is capable of, verifying it should work. Is there any way to make it work correctly as it seems to be a software issue?
I spoke with another AT&T rep who said it doesn't appear to have the region lock as it wouldn't activate on the AT&T network at all then but he didn't know why it wouldn't work. From the article I read the region lock is separate from the network lock. The region lock is removed if a phone call of 5 min is made in the area the phone is from. Then the region lock is deactivated. Here is the article I found. www . androidcentral.com/your-unlocked-euro-galaxy-s7-still-region-locked-thats-not-huge-deal
Would flashing another ROM work, or what level is the incompatibility? In the network settings there are listings for the carriers and their 2G and 3G settings but nothing else.
Apparently this thread double posted so this one can be deleted by a Mod
really... i'm calling BS on the reps... what is your definition of "working fully"? i have a dual sim G935FD and LTE works just fine on AT&T. the international version is missing 2 bands (29 and 30?), that's used in certain areas. other than that, i personally have not had any issues/ have you tried using an AT&T sim to confirm the phone won't work, use LTE? see below as well (WillMyPhoneWork.net):

Hi Everyone,
Telstra here in Australia has dropped their 2g network. The secondary sim on the Galaxy S6 DUOS runs on 2G only.
This has now rendered the secondary sim unable to register on the network and therefor cannot make or receive calls/messages on the secondary sim anymore.
Is there a way to force the secondary sim to be on the 3G network as well? (Thinking firmware?) or is this a limitation of the hardware?
Cheers,
Kris
I recently brought Galaxy S8 SM-G950F (international unlocked) version and use Ultra mobile which in turn uses T-Mobile network in US. I have following queries:
1. Currently Wifi calling is not working nor can I see any options to enable/disable it. Does international unlocked phone do not have this feature? I tried the call setting menu and more connection settings but it does not appear in both of them.
2. After the call connects, my data switches to H or H+ (3G) but otherwise it remains on LTE/LTE+. Is this an issue with my phone or the carrier? My friend uses the same ultra mobile network with IPhone 6s and LTE works while on call so I think its not a carrier issue but not sure. I have heard LTE works on carrier provided galaxy s8 models.
I also have any option to exchange my phone for North America unlocked version S8 SM-G950U. Does this model supports above features? Should I go for this exchange?

You will not get wifi calling or volte on any of the unlocked phones while they are stock. Each carrier is slightly different on what u need to do. Tmobile only need a firmware flash with a carrier that has the option. Att is the hardest, many more steps.
