How to judge whether you can use Retevis RT70 in your country?
Retevis RT70 POC radio is the best selling POC radio wordwide. We all know that different countries and different telecom operators cannot use the same equipment, so how to judge whether you can use Retevis RT70 in your country?
The easiest way to judge is to see if the frequency band of the local telecom operator is compatible with Retevis RT70 POC Radio. The 4G LTE FDD frequency of Retevis RT70 POC Radio is as follows:
| B1 | Tx frequency: 1920~1980Mhz Rx frequency:2110~2170MHz | |||
| B2 | Tx frequency: 1850~1910Mhz Rx frequency:1930~1990MHz | |||
| B3 | Tx frequency: 1710~1785Mhz Rx frequency:1805~1880MHz | |||
| B5 | Tx frequency: 824~849Mhz Rx frequency:869~894MHz | |||
| B7 | Tx frequency: 2500~2570Mhz Rx frequency:2620~2690MHz | |||
| B8 | Tx frequency: 880~915Mhz Rx frequency:925~960MHz | |||
| B20 | Tx frequency: 791~821Mhz Rx frequency:832~862MHz | |||
| B28 | Tx frequency: 703~748Mhz Rx frequency:758~830MHz | |||
If the local operator's working frequency band is within the range supported by Retevis RT70, then you can choose Retevis RT70 public network walkie talkie. Taking Mongolia as an example, there are four telecom operators in Mongolia, Mobicom, Skytel, Unitel, J-Mobil and MCS, and Mongolian Telecom. The operating frequency band as follows:
| № | Licensee | Issued Spectrum licenses | 4G-LTE Band |
| 1 | Mobicom Corporation LLC | 1735-1745 / 1830-1840 MHz 2 x 10 MHz | Band 3 |
| 733-743 / 788-798 MHz 2 x 10 MHz | Band 28 | ||
| 2 | Unitel LLC | 1725-1735 / 1820-1830 MHz 2 x 10 MHz | Band 3 |
| 723-733 / 778-788 MHz 2 x 10 MHz | Band 28 | ||
| 3 | Skytel LLC | 1760-1770 / 1855-1865 MHz 2 x 10 MHz | Band 3 |
Among them, the frequency band of Unitel LLC is 1725-1735MHZ, which is within the B3 Tx frequency of Retevis RT70: 1710~1785Mhz, so Retevis RT70 can be used in Mongolia, using the phone card of Unitel LLC.
