[Q] Straight talk?

[nsh121193]

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

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.
