AT+CGTFT=?
The test command returns values supported as a compound value. If the MT
supports several PDP types, the parameter value ranges for each PDP type
returned on a separate line. TFTs shall be used for PDP-type IP and PPP only. For
PDP-type PPP a TFT is applicable only when IP traffic is carried over PPP. If PPP
carries header-compressed IP packets, then a TFT cannot be use.
