Our 4G service operates on the 800 MHz (also known as band 20).

More Information

giffgaff's 4G service operates on the 800 MHz (also known as band 20), to check that your phone or device is compatible with this frequency:

  • Dial *#06# from your device to obtain your IMEI (International Mobile Equipment Identity) number.
  • Go to http://www.imei.info/
  • Enter your IMEI number from your device & select "Check".
  • You will now receive a free report on screen like the one displayed below.

  • Within the section "LTE" (shown above -highlighted within the red box) it will display what frequencies your handset is capable of sending / receiving.
  • If 800 MHz* shows then your handset is compatible with our 4G services.

*NOTE: There has been information to suggest that O2 (giffgaff operates off the O2 network) is starting to rolling out the 1800 MHz spectrum for 4G use in London and will move on to other cities later in 2016. This means that as well as offering improved capacity the 1800 MHz spectrum will finally allow users of the iPhone 5 to get 4G on giffgaff.

Our 2G, 3G & 4G services use the following frequencies:

Class Service Frequency
2G GSM / GPRS / EDGE 900 MHz
2G GSM / GPRS / EDGE 1800 MHz
3G (H / H+) UMTS / HSDPA / HSPA+ 900 MHz
3G (H / H+) UMTS / HSDPA / HSPA+ / DC-HSPA+ 2100 MHz
4G LTE 800 MHz
4G ** LTE Unconfirmed 1800 & 2100 MHz

**NOTE: There has been information to suggest that O2 (giffgaff operates off the O2 network) is starting to rolling out the 1800 & 2100 MHz spectrum for 4G use in London and other areas and will move on to other cities later in 2017. This means that as well as offering improved capacity the 1800 & 2100 MHz spectrum will finally allow users of the iPhone 5 to get 4G on giffgaff.
