    Yes. 4G is backwards compatible to 3G, and 3G data is backward compatible to GPRS (2.5G, but it in unlikely that you will find 2G (GSM) anywhere; if you do, you would need a modem to transmit data, as GDSM had no digital transmission) Aug 6, 2018 at 9:32
  • Since you posted in the IoT section, we have to assume you are asking about 4G vs 3G/2.5G for data transmissions. As a general rule, the higher the 'G', the more speed you get. 4G is generally associated with the LTE standard, which in the right circumstances, can get you at least 1Gb/s.
