Solavei Phone Compatibility Advanced

Solavei Phone Compatibility Advanced


Mobile phones come in a wide array of hardware and software. Because many phones are made for specific wireless carriers in the USA, they are often not compatible with other wireless carriers. There are 2 main reasons a phone’s hardware may or may not be compatible with Solavei.

Mobile Phones Use Different Technologies

GSM and CDMA are the 2 technologies used in the USA and are they are not compatible with each other. Solavei uses GSM based technology and therefore, CDMA phones will not work on our network. You can think of it this way: CDMA phones speak a language the Solavei network does not understand. 
 

Mobile Phones Use Different Frequencies

Each wireless carrier owns a certain set of radio frequencies that their cell phones work on. This means that if a phone uses a different set of radio frequencies than Solavei does, that phone won’t be able to use the Solavei network.

You can think of this in terms of radio stations. When you change the dial on the radio in your car, you receive a signal from different radio stations. Mobile phones usually can only pick up a few different frequencies. If your radio station could only pick up 3 radio frequencies, you would only get those 3 stations. A friend’s radio that picked up 3 different frequencies would get 3 different radio stations. This means that your friend can’t get the same stations as you. In phone terms, a phone that works on AT&T uses different frequencies than a phone on T-Mobile does.

Phone Frequencies Advanced


Solavei's current frequency map:

  • 850 MHz – This is mostly voice roaming in the USA.
  • 1900 MHz – Voice - Now transitioning to support 2G, 3G, and HSPA+ 4G data. 
  • 1700 MHz - 3G/4G Uplink Only
  • 2100 MHz - 3G/4G Downlink Only
  • AWS Band 4 (1700/2100 MHz) - LTE Uplink and Downlink
  • Band 4 LTE

In all areas of LTE coverage on the Solavei coverage map, a mobile service user can expect to receive LTE data coverage, HSPA+ 4G (on both the 1900 and the 1700/2100 AWS spectrum), or 3G data depending on the supported frequencies and speeds of the device they are using.
