I have a galaxy s5 G900A that I had unlocked and I put a tmobile sim card in it. Anytime I am outside of tmobile service my phone will show that I have bars but I can't use voice text or data. I try to connect to at&t or Verizon's network to roam and it won't connect. Is there something I missed when unlocking that will allow my sim to roam on another network? Or is this something tmobile is doing wrong on thier end? My girlfriends galaxy s4 has the same problem.

How can I make my HTC Magic roam on ATT's 3G network instead of Tmobile? We don't have 3G coverage on Tmobile in my home town, but I would like to see if I could get the phone to work on ATT's network. I have rooted my phone and it's not unlocked. If I unlocked the phone could I use the Tmobile SIM card on Att? I've also tried selecting ATT's network, but it won't switch. Thanks for the help.

There is not a way to make your phone show ATT if it is in coverage range of T-Mobile plus the 3G network on att uses a differenty frequency than Tmobile does so even putting a ATT sim in an unlocked mytouch or g1 would not show 3G.
I feel your pain i am waiting for cincy to get 3G as well.
Got this error message when using a TMo SIM in a Verizon G2. I've only seen one thread about this for the G2.
Verizon G2s are SIM unlocked, right? So it shouldn't be a problem? I can put the TMo SIM in a TMo branded S2 and get full bars. I even tried the same SIM in a Verizon Galaxy S3 and got full bars.
I'm on VS98012B
As a follow up, I went into available networks and this time, TMobile at AT&T show up. I tried setting it to WCDMA and GSM but it wont register on the TMobile network.
This is a location that I can normally get LTE.
The VERIZON model is GSM unlocked. Says your on 12B so you should be good. You should be able to just pop and go. I don't have much experience with it but you would have to select GSM in the Network Settings.
I have read all the guides for unlocking the SIM for GSM networks. But What I'm trying to do is use my Sprint LG G2 LS980 on my Verizon Account.
I have gotten the unlock SML from Sprint for the device and I know both networks are CDMA, so I should be able to put in a Verizon Sim, enter unlock code, the BOOM! Have my Verizon plan.
But when I insert the Verizon SIM card into the phone it says "No SIM card - Emergency calls only"
Why wont it even detect that there is a SIM card in the device.

It won't work anyway...the voice network is CDMA, meaning that the serial number needs to be whitelisted by Verizon for the device to work. Unlocking only works for GSM devices; you might be able to use it on AT&T or T-Mobile (3G mode) since the UMTS network should work there.

Call the new network now so you can port it from the old network
I have a SM-935 U device and have been using on the AT&T network. I recently switched to Verizon MVNO (US Mobile). The phone doesn't get registered on the Verizon network. I bought the unlocked S7 edge from best buy thinking that it will work on all carriers. Any help will be appreciated.
The SM-935U do work on all carriers. I have a SM-935V with U firmware on it. I'm with a Verizon MVNO named Total Wireless. Sounds like the phone you go from Best Buy is stilled registered under AT&T...
Not getting registered to Verizon network
When I check the IMEI of my phone against the Verizon compatibility check using their web site, it is fully compatible. The issue is that phone is not getting registered to the Verizon network. I think Verizon is blocking it some how and the MVNO is not able to help me to resolve this.
You ever figure out a solution out to this?

The LTE should work fine, but youll have to set the APN correctly, otherwise it wont get any data, for the CDMA portion youll have to submit the ESN to Verizon to add your ESN IMEI to their database.
I just got my S8 unlocked from Sprint, the UICC says it's unlocked for all sims in the settings. But I've tried both an AT&T sim and a T-mobile sim. The tmobile splash screen comes up and it even shows the tmobile phone number in my about phone settings, but I can't get any data or calling or anything to work. Same for AT&T. It even says AT&T up in the top as carrier but nothing works.
Do I need to do something like flash it, or is it possible they only did international unlock is why this is happening? Or is it because I still have Sprint service on the phone? All I know is in settings area for UICC it says any sim will work, but it's not working.

Sometimes service is dependant on the apn settings. Check those and make sure network settings are swapped to global. Also radio switcher app.
Lastly the sprint firmware may not have needed bands enabled. These are all the things to check first
