Asus PadFone-X Mini 4.5" Smartphone + 7" Tablet

Can i use this device worldwide with another carrera?

I’m sure you could use this in any Porsche you wanted.

Can this phone be activated on Verizon network?

same question. Verizon?

I can’t say for sure, but a couple things that are good to know

  • It supports much more than AT&T’s specific radio frequencies
  • AT&T will carrier-unlock a device for free if you don’t have an active AT&T account. I just did it a few months ago for the Sony Tablet P I bought on Woot! years ago. They did it in about 48 hours without a fuss - I just needed contact info and the IMEI of the device.

does the phone come already unlocked?

Per the specs, it will work on these networks:

GSM/GPRS/EDGE/LTE - AT&T (SIM not included)
GSM: 850MHz/900MHz/1800MHz/1900MHz,
WCDMA: 850MHz/1900MHz/2100MHz
LTE Bands: 1900MHz/1700MHz AWS/850MHz/700MHz

Can I use this phone out side of US country, like Singapore with its local carrier providers, because I usually travel to Asia countries ?

This thing is actually pretty rad! It’s got surprisingly nice displays in both phone and dock. It’s not too bulky, either.

I’m just waiting on AT&T to give me my unlock code and I’ll be set!
