[Q] Straight talk? - LG Optimus G Pro

Has anyone used this phone with straight talk? do you need to unlock the phone or will their sim card work instantly?

I'm using my AT&T Optimus G Pro with Straight Talk. Works great. If it's a GSM phone you can use Straight Talk.

No. Their sim card will not work unless you have the phone network unlocked.

Yes mine is the AT&T version as well, did you need to unlock your phone? I have seen some saying you do and some saying you don't, but most people aren't on it it's just their thoughts. Since you are on, did you?

I didn't have to..that's the beauty of GSM phones. Most GSM doesn't necessarily have to be unlocked because most use the same frequencies. Also, I could use my Sim card on a T-Mobile phone, if it was GSM.

I bought mine already unlocked so I have had no issues whatsoever using Straight Talk. Love getting 4G for 45 a month.

Quick tip if you use straight talk all you need to order i straight talk att sim card. That gives you full 4g... If you use the straight talk t mobile sim you'll only get hspa +. If you have the t mobile sim then you'll need to unlock the phone and then set the phone up for T-Mobile network.
Add there is no need to unlock the phone.

I have the AT&T G Pro using Straight Talk. I had to network unlock mine. I verified this by putting the ST AT&T sim in before I unlocked it just to be sure and it did give me the "Invalid Sim" error. So this phone IS network locked. AT&T's provisioning is different than Straight Talks. So just because it's an AT&T phone and AT&T compatible sim doesn't necessarily mean it will just accept the sim without network unlocking.

I also have the AT&T G pro. ordered the at&t micro sim from ST and inserted and it worked without having to unlock the network lock. In fact on all of the AT&T branded phones i have used i have never ever had to unlock to use a ST sim card that used the at&t network.
In fact if you go to this link http://www.straighttalk.com/wps/portal/home/shop/sims
it will ask you if your phone is t-mob or AT&T and as long as you get the right sim for your phone, you should not have to unlock it.
I did have to edit my apn and follow the instructions in the thread below to get mms working
http://forum.xda-developers.com/showthread.php?t=2761126

I didn't have to unlock my E980, as I used a AT&T compatible Straight Talk SIM. I get full LTE no troubles, but you have to fool with APNs to get MMS, as with most third-party carriers on other carrier's phones.

[Q] HELP! Can I switch the AT&T S3 to Verizon?

I have Verizon, a Motorola Razr (Not MAXX) and it is crapping out on me, running slow, not sending picture messages etc.
My boyfriend has a trading post type store and he bought a brand new Galaxy S3 but it's through AT&T. When I put my SIM card in the S3 it asked for a SIM Pin for unlocking.
I have experience rooting a Nook Tablet so with some directions I'll probably be able to do it, I just don't know where to even start. Do I just unlock the phone or is there a way to switch it over?
Thanks!!

It seems like you just need an unlock code to use it with your old SIM.

Try taking a look at this thread and see if you can get an unlock code from AT&T.

So I called AT&T and they gave me the unlock code. I used it and it said unlocking the mobile network was successful. I tried to make a call and it said that only emergency calls were available. I restarted the phone and when making a call it said no mobile network can be found.
Ohhh you are putting a Verizon sim card in it? I don't think that will work since Verizon's network and lte use different technologies than at&t and the sim card is encoded to use the respective technology :X

Yea I have a Verizon SIM card. On my verizon RAZR I have the option to switch betwee CDMA/LTE, Global, and GSM. I know AT&T run off GSM but if my Razr has the option to switch does the S3??

That would mean you can insert a gsm sim card into the RAZR maxx because it is a world phone. However, the at&t s3 does not support CDMA, which is the network technology that Verizon uses. That's probably why you are getting no mobile network when inserting your Verizon SIM card in the AT&T s3.
Sent from my SGH-I747 using xda premium
The gsm sim that comes in Verizon global phones is there so when you travel out of the country you can use a cdma phone in countries that have a primary backbone that is gsm. In the us your phone uses Verizon's cdma network. If it does not see that network it will then look to the sim card to see if global gsm networks are detected.
To my knowledge this is going to be a no-go. If you have not done so, clean up your sd card, toss a factory data reset at your razor. These android phones are pretty tough.

From what I have seen you can turn it into T-Mobile AT&T I don't know if its because I have my sprint service on it or what I know it is possible though.

Can't get Unlocked LG-E980 to go on LTE while on AT&T

I have an LG-E980 (Optimus G Pro) that I bought at an AT&T store, unlocked, used on T-Mobile for a year and now I am using on AT&T (the carrier for which it was made), but under no circumstances can I get it to acquire LTE signal.
Just a few things to note:
1. I unlocked it when I first got it by paying for a code to be sent to me (which it was and I was able to unlock it immediately) -- It was not AT&T that unlocked it for me.
2. I do remember seeing the 4G-LTE once while on T-Mobile
3. My AT&T account is set up for LTE access (verified at AT&T store)
4. My SIM Card can access LTE network (verified by putting my SIM in an LG-G3 that belonged to one of the AT&T store employees)
5. I am currently using a rooted stock LG-E980 ROM (KK 4.4)that was "restored" onto the phone rather than flashed.
My last option would be to put my SIM in a LOCKED E-980 and see if just because it is unlocked it can't access the AT&T LTE network. Any suggestions are welcome.
Thanks,
Mike

Should be an easy fix man try setting your apn again just one letter or word wrong and it wont work.....
Set
Name= ATT Phone
APN= either iso or ndo cant remember
mmsc=http://mmsc.att.wireless.net
mmscproxy= proxy.att.wireless.net
port= 80
350
150 those last two vary on region
apn type= admin,default,mms,hipri,supl
It works for me and did the exact same thing.
I am on cricket but the networks are the same and apns dont distinguish all my asop roms say ATT,
Or you could use the AIO one
Cricket Aio Wireless
ndo
http://mmsc.aiowireless.net
proxy.aiowireless.net
80
350
150
default,mms,fota,hipri,supl

I just picked up a Verizon S8+ (i had a T-Mobile one but just returned it) and i popped a T-Mobile SIM Card in it and i got a message saying "This is not a Verizon Wireless SIM Card" and it wouldn't let me use it. I thought it was supposed to be unlocked??
It is unlocked. After swapping Sims the only change you got to make is change preffered network mode from LTE/CDMA to LTE/GSM oh and go to APN and choose your new sim card apn. And thats it. Ive tried all carriers on my Verizon S8+ with no problems

What probably will not work on any carrier phone other than TMobile will be WiFi calling when using TM SIM.
Hey! I need to know if I buy a s8+ in Verizon, I will can use in Chile with my local carrier? I can read that you don't have problems changing the carrier in USA, will be the same if I use the phone with a Chilean Sim? Thanks!
I have a Verizon S8+ on AT&T unlimited service and it works perfectly. So you'll be good for Tmo as well. I have no clue about Sprint tho.
I have a Verizon S8+ on att and it works great. Does anyone know if I get HD Voice with this combination ?
Verizon unlocked S8 plus on T-Mobile working flawlessly for me
Verizon unlocked and works very well in France on the Orange network.
When I got my VZW S8+ I popped in my tmo sim first thing. It worked flawlessly out of the box. I didnt even have to add any APN settings as all of the tmo settings were built in. Awesome job sammy!
What about video call ect I'm having issues getting that **** to work is u pres *#77467# it says false on all the **** why won't the ims register that controls all that
I have an issue with s8+ using AT&T sim. The issue is that the phone shows a plus sign in front of my all incoming calls treating them as international calls. Does anyone know the solution?
The phones are completely unlocked, what you need to do is look up the VPN settings that T-mobile, or at&t use for their phones and set them accordingly. Though some functions might not work with non-Verizon carriers through changing these functions. (messages, video calling, etc..)
Thank you all. I bought the s8+ from Verizon out right because I wasnt sure if I was going to stick with them. And it looks like I am moving to t-Mobile this month, I was going to look into flashing the firmware, but I was worried since I used Samsung pay like crazy. So I am fine with just disabling the verizon apps and going from there.
Anyone know if the phone will still get updates if I swap in a T-Mobile SIM, or a Verizon-compatible one from Straight Talk while still on the VZW firmware?

It will if you use the VZW software update assistant. I've done 2 updates this way on my Verizon S8+ with my tmo sim in there. Works fine.

Sounds good. Do you know of the Verizon phone has all the bands of the T-Mobile version?
Fully work - no. Things like HD calling and wifi calling wont work without t-mobile software.

Can I use a unlocked T-Mobile S8+ on VZW

I have a unlocked T-mobile S8+ and when I put my sim in the phone it doesnt register on the their network. I thought I read all the S8+ have the capability to work on all networks.
Thanks in advance
Have you tried flashing to the G955U1 firmware?
I haven't yet. I will try

Are you using already active sim card? just curious.
Yes it will. The US varient are all the same for every carrier so it should work fine.
After many attempts nothing worked it looked like the T-Mobile verison is missing the cdma bands to make calls

So you flashed to the 955U1 firmware & inserted a preactivated Verizon SIM card and it still didn't work? Did you domestic unlock the T-Mobile S8 first?

What color is yours? I use an Orchid Grey S8+ from verizon but I use my tmobile sim in it. Worked right off the bat without any APN changes. Maybe we could trade. I would rather have the tmo bloat that I could actually use rather than the vzw bloat.

Those unlocked at&t or tmobile phone won't work for Sprint or Verizon. Sprint and Verizon required the IMEI in their database.

I'm late to this thread, but what I did was make sure my S8+ (T-Mobile variant) was paid off and then I used the Device Unlock app. It did not work at first. Then, I inserted a Verizon SIM and rebooted the phone. I relaunched the Device Unlock app and selected the option for Permanent Unlock. It worked and then asked me to reboot the phone once more. Once I did that, it took me to a blue screen while it loaded the Verizon bands and apps and then rebooted one more time. It works flawlessly and even loaded the Verizon boot up screen.
From what it seems, all of the USA SM-G950/955 units are indeed capable of working with other networks and will load the appropriate firmware of that carrier but, at least with T-Mobile, the phone must be paid off first and then the Device Unlock app must be used. It is working great on Verizon as if it was sold to me by them.
