A:AnswerSony just got the phone certified through Verizon (https://twitter.com/SonyXperiaUS/status/1024731663979433985). You can use Verizon but are probably limited to LTE only coverage.
A:AnswerI have only used it with cricket (a GSM network), but the Sonymobile website lists its network information as:
GSM GPRS/EDGE (2G)
UMTS HSPA+ (3G)
LTE (4G) Cat13/Cat12
Certified on Verizon networks
Sonymobile was giving these instructions to some Verizon users with unlocked phones:
Existing Verizon Users:
Step 1: Update Firmware on your XA2 device
a) To update your Xperia™ device, find and tap Settings > System > Software Update. Then follow the on-screen instructions. You can also update with a computer using Xperia™ Companion.
b) Update the firmware to Software version 50.1.A.12.9 or greater.
Step2: Activate Verizon Bring Your Own Device profile
a) To activate or use an existing number on a new BYOD device, please ensure to log in to your account on verizonwireless.com > My Verizon > My Device > Activate or Switch Device and follow the instructions. Otherwise, call Verizon customer service center for CDMA-less
For New Verizon Users
Step 1: Update Firmware on your XA2 device
a) To update your Xperia™ device, find and tap Settings > System > Software Update. Then follow the on-screen instructions. You can also update with a computer using Xperia™ Companion.
b) Update the firmware to Software version 50.1.A.xx.yy or greater.
A:AnswerGenerally speaking unlocked phones mean they're GSM unlocked and Universal unlocked phones are typically compatible with CDMA carriers like Sprint and Verizon. Verizon lately has allowed certain phones to be certified to work on their network as an LTE only device and the XA2 as of today is certified to work on Verizon. Keep in mind that you have no 3G fallback so if LTE coverage is lacking then this might not be the phone for you.
A:AnswerIf you're asking can the Xperia XA2 use a SIM card from Straight Talk for service, then the answer is "Yes."
Since the phone is Unlocked, it can take any GSM SIM card. In fact, in my Xperia XA2 right now, there is a SIM card from Red Pocket, a MNVO like Straight Talk.
A:AnswerIt should work for following networks and frequencies at the very least
NETWORK 4G LTE FREQUENCIES
CDMA 1900, 1700/2100, 850, 700
GSM/HSPA+ 1900, 1700/2100, 700, 600
A:AnswerNot in the version that I purchased from Best Buy and later returned since the phone not supports WiFi calling when using a T-Mobile subscription
