Hi
I have a galaxy s8 given to me supposedly unlocked, (I don't know, it still says this sim is not from verizon) but when I put in my Jio sim, it does show that the network is Jio and also shows 4G. However, I cannot make calls or receive calls. When I call the number, it says switched off, though the phone is on and the network says jio 4G.
My question is, is it possible to root this phone, remove the existing Verizon based ROM and install an India based ROM.
The phone model is SM-950U
Thanks in advance, I am a newbie.

Hi,
Recently got a Koodo GTi9020A and have tried to use it in the UK with a 3 Sim.
The phone gets a full 3G signal, data and internet work, however there is a problem with making calls when using the 3G signal.
When the phone is turned on I can make one call to a landline, however if I hang up and dial again there is silence. Calls to other mobiles are scrambled.
I have spoken to Google and have been told that the Canadian software will not work with a UK Sim and the phone will need flashed with UK software.
The phone is therefore 'locked' to the Canadian networks. The lady from Google mentioned that a fully unlocked phone would be more expensive!
Any advice appreciated.
Thanks.
I recently bought an unlocked Google Nexus S from amazon. The Device works fine on ATT network. When I got it to India and tried inserting an Airtel SIM in it. The phone shows complete Signal strength but says emergency calls only. On the lock screen it says insert SIM.
When I search for available mobile networks it shows my network but unable to connect to it. It does not even ask for unlock code when I insert a SIM from another carrier.
Is this because the phone is locked or is there some other problem?

What network frequencies does Airtel use? If non of them match that could be why, oh and Nexus phones are never network locked
Sent from my ice cream powered Nexus S
Yeah, frequencies should be the reason here.
But only for 3g, the us always being special, especially at&t. ^^ 2g should work worldwide. Set it to "2g only" and see... (if it works, slow data, but at least you can make calls)
I got a Samsung captivate from ATT and it worked also my Galaxy S 4G. All these are quad. band phones so, they work worldwide. Could be some other problem. Got a good deal, so dont want to return it, but I guess I have no option now.
Tried a new sim?
im gonna be going to india in a month or so and i wanted to know if the i9020a will atleast work with voice in india. airtell or vodafone it doesnt matter. I don't need 3g but i was hoping voice would work so i could just use this phone in india.
did you try to reset the phone?
Hi, I bought the Samsung S8 US Unlocked version from Bestbuy in US. I recently moved to India and when I tried Airtel or Jio Sim, I dont get the network and not able to place voice calls. However when I goto Network selection am able to see the right network selected (respectively for whick network's sim I used).
Can I use an US Unlocked S8 in India? If so, how to make it work. Am stuck, please help!!
Edit: 4g LTE is working, but not the calls. If I have the sim put in another phone, able to make calls. Not sure whats wrong in S8 with placing the calls when 4G LTE is working??
I am using a sim unlocked T-Mobile A71 5g with a cricket sim. VoLTE does not work. If I flash the AT&T firmware onto this will it allow VoLTE to work? Will it relock the sim unlock? (I highly doubt that is the case, but want to cover my tail.) Will it allow me to use LTE band 66?
Thanks
HOw is Cricket not blocking your acccount? I bought one for my mom and its unlocked for ATT network and it works for like 5 mins and then says its not compatible. I masked imei with ed exposed and still cant get it too.

Hey if it's rooted you can use short cut master lite and open Cid manager and it will change your csc and network you can pick AIO which is Cricket .
I am not rooted. I heard that that google pay and Netflix quit working if you root a phone. Haven't tried rooting a phone in the last 3 or 4 years. Kinda out of the game.
I am having a similar issue. My phone is an unlocked T-mobile and on AT&T TOGO. I keep getting my outgoing calls redirected to AT&T cust srvc. They say my phone is not VoLTE capable and therefore will not work after 3G sunset. T-mobile support site says VoLTE is enabled by default, just that there are no settings to turn it on or off. Wondering whether it's safe to flash with AT&T ROM? Or maybe generic Samsung ROM if available?
Please I'm in Nigeria, i bought this A71 5G front a vendor at second hand. But my local sim card won't work on the phone.
How do i unlock sim?
Hi,
I use my international variant S7(sm-g930f) on the ATT network, and they notified me that my phone will not work on their network in February 2022 because they are shutting down 3g in my area. They say my phone will not work on hd voice.
Two things I notice is that my phone does have 4g lte, and the ATT variant S7(SM-G930A) will still work.
Is it possible to make my phone still work on their network by installing ATT variant firmware?
Thanks
