Some friends from North America order the Android screen with 4GB RAM +64GB Rom, since this is low configuration, it only contains European & Asia 4G LTE version, In this case, It might NOT support North America
(US or Canada) 4G Network.
EU + Asia version and North America version Comparison:
Europe & Asia:
GSM: 850 / 900 / 1800
WCDMA: B1, B5, B8
TD-SCDMA: B34, B39
FDD-LTE: B1, B3, B5, B7, B8
TDD-LTE: B38, B39, B40, B41
GSM: 850 / 900 / 1900
WCDMA: B2, B4, B5, B8
TD-SCDMA: B34, B39
FDD-LTE: B2, B4, B5, B7, B8
TDD-LTE: B38, B41
The above comparison list indicate: Some EU & Asia network provider might not offer the model for North America market, for example, the FDD-LTE: B1 & B3 are not in North America, but if you choose B5, B7, B8, it also on the list of North America, thus, it compatible.
Thus, if you decide to use 4G LTE, we recommend you to choose
"8GB +128GB" or "8GB +256GB", it can made with North America 4G LTE.
Questions you might have:
1, What is the 4G LTE ?
The 4G LTE function is enable you to insert the 4G Sim card (you have to buy a Sim Card from your local network provider and choose data plan),
With 4G, you can connect the android screen to internet always, such as use the Google online map, or hearing the online music, etc.
Yes, you can
The android screen built-in WIFI, without 4G, you can also connect the android screen via hotspot (from your phone) and use online service (navigation ,music, video etc). Or you can download the maps or music to android screen and use it as offline (it not cost internet data when using them as offline mode).
Yes, you can.
The 4G LTE function has nothing to do with the Carplay/Android auto function, without 4G LTE, you can also connect the phone via Bluetooth
