You'll need a 3G or 4G compatible phone to use SMARTY. Not sure if your device is 3G or 4G? No worries...
Follow these steps to find out:
Dial *#06# on your phone to display your IMEI number.
Go to www.imei.info, enter your IMEI number and select Check.
You’ll see a report. Look at the LTE section – it will display all the frequencies that your phone is capable of using.
Our 4G service runs on the 1800MHz frequency, so if you see 1800 in that column, your phone is 4G compatible. We also support Supervoice (VoLTE @ 800 MHz) and WiFi calling.
Our 3G service runs on the 2100MHz frequency so if you see the number 2100, your phone is 3G compatible.
