The table below lists the operating frequencies for the Singapore Radio Network within Singtel (roaming networks may differ). Any device in use on the network must be equipped with a suitable radio module to utilise the technologies below. Devices must conform to 3GPP (release 11) standards.
| Band | Mode | Frequency (DL/UL) [MHz] | Bandwidth [MHz] | Technology Deployed | 3GPP Release | Time between location updates [Hours] |
| 1 | FDD | 2125-2140/1935-1950 | 15MHz | UMTS | 11 | 1 – 2 |
| 3 | FDD | 1865-1880/1770-1785 | 15MHz | LTE | 11 | |
| 8 | FDD | 925-935/880-890 | 10MHz | GSM & UMTS | 11 | 1 – 2 |
| 20 | FDD | 791-801/832-842 | 10MHz | LTE | 11 |
Please keep in mind that all the details above apply to the connectivity inside Singapore. We recommend testing your connectivity when roaming to check that everything works as expected.
