Network operators on the different continents use different frequencies, and not all devices support all network frequencies.

Also when using a dual or triple SIM device, insert the Surfroam SIM card in SIM SLOT 1, since this slot often supports more network frequencies then SIM SLOT 2 (see device specifications or manual)

The frequencies can roughly be divided as follows:

Africa:

2G: GSM 900 / 1800 Mhz

3G: UMTS 900 / 1800 / 2100 Mhz

4G: LTE 1800 / 2100 / 2300 Mhz (very limited available)

Asia:

2G: GSM 900 / 1880 Mhz

3G: UMTS 850 / 900 / 1500 / 1700 / 2100 Mhz

4G: LTE 850 / 900 / 1500 / 1800 / 2300 / 2500 / 2600 / 3500 Mhz

Australia:

2G: GSM 900 / 1800 Mhz

3G: UMTS 850 / 900 / 2100 Mhz

4G: LTE 700 / 850 / 900 / 1800 / 2100 / 2300 Mhz

Europe:

2G: GSM 900 / 1800 Mhz

3G: UMTS 900 / 2100 Mhz

4G: LTE 800 / 1800 / 2600 Mhz

North America:

3G: UMTS 850 / 1900 / 1700 / 2100 Mhz

4G: LTE 700 / 800 / 1700 / 1900 / 2100 / 2300 / 2500 / 2600 Mhz

South America:

2G: GSM 850 / GSM 1900 Mhz

3G: UMTS 850 / 1900 / 1700 / 2100 Mhz

4G: LTE 700 / 1700 / 1800 / 2100 / 2600 Mhz

When travelling to a specific country on a specific continent, please make sure your device supports the local network frequency.
