[Q] International Roaming - Sprint HTC One (M7)

Hi guys,
I'm in Europe trying to use a US T-Mobile SIM to roam internationally but I get no service period. I'm on Insertion 8.1.3 I have done the SIM unlock in the past and had Sprint do the Uicc Unlock. But still nothing do I need a different SIM like Vodafone? My friend has a Verizon Galaxy Note roaming no problem.

[Q] Sim Card Error

Hi,
I have recently bought a MotoX Sprint XT1056 not developer ed. I have unlocked the phone using this guide from on youtube watch?v=sw675ipX-ds
It is unlocked now and I can detect the network operators available but cant register to any. There is a red triangle with a white + on the celular signal icon. The sim I am using was tested on an iPhone 5 and works, using an micro sim adaptor it works on my S4. The sim is cut, however using a proper nano sim it still says sim error.
I would really like to use the MotoX I think it is a really solid phone and feels good at hand, what could the issue be??
You have unlocked bootloader of your phone, that does nothing with sim lock. Sprint devices are locked so you should contact them before you can use them in other networks
I have looked around the forum and other sites. Is sprint moto x a gsm phone or cdma? Because I can detect gsm networks. But cellunlocker says my phone is not gsm. Anyone can confirm it?

Sprint and Verizon use CDMA on their networks for Voice and 3G data, however they include GSM bands for "global roaming capabilities" and also support LTE.
Sprint ships their phones with the GSM side sim locked. Verizon's X is shipped Sim UNLOCKED. (this is separate from locked/unlocked bootloader).
There are a few threads I've seen about people trying to use Sprint Moto X with the SIM of a GSM carrier and running into difficulties due to the SIM Lock. I haven't seen any "this is how I sim unlocked my Sprint Moto X and got it working on a GSM carrier" type posts. I've seen a few suggestions of "call sprint to try and unlock." This might work, but it might not. Some carriers have rules around sim unlocking... (must be current customer, billing must be current, have to be customer for xxx days, etc).
How to get the unlock window to pop out? Inserting a foreign sim doesnt seem to make it work.

[Q] Use SM-G900A (AT&T) in Europe?

I believe the answer to this is "no", but:
I have access to an AT&T SM-G900A that is not being used. My daughter is about to move to Germany for an extended period.
First, can the phone be used in Europe at all?
I certainly wouldn't want to pay AT&T's probably-exorbitant rates, so then: can we buy a SIM card there to use in it as is? (pretty sure the answer is "no")
If I unlocked the phone (by buying an unlock code), could it then be used with a Europe-purchased SIM card?
I suspect this is all more trouble than it's worth and I'm better of just finding a used unlocked GSM phone of some sort.
Much thanks.
if you can use it abroad unless you unlock it first.
I have a galaxy s5 att and I am using it with another carrier here in south america.
only bad thing is that the wifi hotspot will not work for being a simcard from another operator, only work by usb tether.
It's working well. I bought an AT&T Galaxy S5 from USA and now I use it in Romania.
The WiFi hotspot is not working, but all the other features work very well.
Probably, after the bootloader will be cracked and we will have the opportunity to install a custom rom or an unbranded rom, the hotspot will function as well.
Enjoy your gadget !
All answers are correct. I was formerly in the U.S.Army and took an old T-Mobile HTC Dream over to Kuwait with me. I called T-MO and got a sim unlock code for free. Upon getting overseas I established service with a GSM carrier over there and popped in my sim card and whallaa! My phone completely worked in Europe and the middle east.

Sprint Note 5 swapping between AT&T and Sprint?

Just got my Sprint Note 5 domestically unlocked so I can switch to AT&T, question is should I just be able to up my AT&T sim and It should work OK? Can I swap back and forth with my Sprint sim and my AT&T sim? My sprint contract isn't up till end of October and I already have my AT&T sim, just not porting my number over yet.
Did you ever figure this out? Im curious to know how easy or hard Sprint makes this.

Can i get lte with Tmobile g6 but Verizon service?

I'm on Tmobile now but going to Verizon soon but would like to buy a Tmobile g6 and unlock it. So what the title says, I know service will work but will I get lte through Verizon on my Tmobile phone. I used Tmobile in Verizon phones no problem and got lte before.
It depends on what radios the Tmobile G6 supports. I believe it has a sim card slot for the smaller sim cards verizon uses. I would google tmobile g6 radio and verizon radio bands and compare.
Also if I am not mistaken you will have to unlock the phone in order for it to accept another carrier. I believe if you buy the phone outright, tmobile will send you instructions for unlocking it.
Ok. I'm ordering the factory u locked g6 with dual sim. Hopefully it fully support cdma
I would also be interested in knowing if it would work or not.

T-Mobile generally requires a device be on their service for 40 days before unlocking it. Something to keep in mind.

once unlocked you should be able to use LTE, but only for data. Most likely it will NOT support VoLTE (HD voice ) and VoWiFi.
I bought a used tmobile lg g6, used the unlock app to permanently unlock, but can't get it to work on verizon network. I inserted my verizon sim card but just tells me network is unavailable
Verizon refused to accept the imei for my t mobile G6. So I refused to remain a Verizon customer.

Verizon Gs8 on other carriers?

Hey all. Just wanted to see if any one could answer this. Since all the major carriers sold the same model then each phone should be able to work on every carrier. More specifically I have a Verizon gs8 wanted to know if it would work on sprint or even t mobile. I did pop a sprint sim in here and it wasn't working but I didn't mess with any settings. I'm also running unlocked firmware. Does anyone have this phone running on sprint or t mobile? I did call sprint but they said my imei wasn't present in their database so they couldn't garuntee it would work. Thanks

I have a Verizon Samsung S8, that worked fine with T-mobile with few issues.
- WiFi calling can't be enabled on non Verizon Sims
- Voicemail would by default direct you to Verizon voice mail service
- Kept getting an error every time I restart the phone that the sim is not from Verizon
