New Straight Talk Bring Your Own Phone (BYOP) 3 size in 1 SIM card Kit AT&T Compatible

Worked perfectly. Bought it to use for my Sony Xperia XA1 Ultra unlocked phone. I knew going in that the phone, being GSM, would only work on the AT&T network through Straight Talk. You activate the SIM card the same way you do a new phone bought directly from ST, except you enter the SIM card number instead of the phone serial number. My advice: activate the card first, THEN insert it into your phone. I didn't realize the number wasn't printed anywhere else and had to take mine back out. The longest part is waiting for the old phone to stop working and the new one to work instead. Took about 15 minutes for me. Be sure to restart both phones after the new phone gets service. I almost immediately got a call from ST verifying that everything was working and offering help if my mobile data wasn't set up properly (it worked fine, no help needed). The network is fine. There are a few known dead spots in my building at work, and they didn't improve on my switch from my old phone on the Verizon network. But no worse either. My phone is connecting through LTE 95% of the time, and calls are great. Would definitely purchase again, as long as you're familiar with Straight Talk.

Bought this for a phone that I purchased for my son for Christmas. At first I thought it wasn't going to work on any of the SIMs cards we received, but the final one was it. It was nicely packaged and arrived on time (if not early) and was easy to install. There was no problems with the SIMs cards, just the phone (purchased elsewhere) was finicky.

This is NOT an At&t sims card, I needed specifically an At&t sims for my phone from the description it says it is and if you ask the AI on here it will say it is but it is just a T-Mobile and a Verizon sim, the same thing Walmart has for $4

Great price, comes with what you need to switch your phone over to straight talk.

I hate calling people on the phone but this worked and worked as described cant compliance.

I am quite ignorant when it comes to tech gadgets etc.less is more,simplicity is key.i have been a strait talk fan for 10 consistant years and I never spend more than $70 on a phone,and have it for years.i bought a phone a couple weeks ago a SAMSUNG 8S active,unlocked,spent $300,that's me being fancy.With little confidence and knowledge I bought this SIM KIT to activate which came with AMAZING INSTRUCTIONS FROM SELLER.And it ,though straitforward,fell apart on strait talks side.BUT WAIT.....MY EVEN MORE CUTE BUT DUMB MAN SAID DAIL 611.I did.in less than 4 minutes I not only hooked up my phone and data but also kept my same phone number. This three-in-one SIM card kit does work. It really is so super simple. Just dial 611 And listen to the instructions. It really is that simple.. If I can do it anyone can I promise.

Best sim to use to bring a new unlocked phone or existing straight talk customer with unlocked phone. Has some connection to ATT that straight talk likes you to use better. I have no connection to ATT but Straight Talk advised me to buy this specific card for easiest transfer of an unlocked phone. I used another sum for straight talk first and messed transfer up and couldnt use it twice. Buy this card for sure. No negatives as I can see. Works seamlessly.

I gave a family member an old phone of mine, and they have straight talk. My old phone needed Verizon towers. So this worked for that. They actually give you 3 choices (I believe it’s 3), which is super cool! Our other choice was possibly buying the Straight Talk sim kit with the unlimited plan, and we did not need the monthly plan. Just the SIM card. That would have costed much more. So this was awesome! Very easy to install.
