No, it is too far away and the smartphone does not have enough power for that. A terrestrial terminal would connect to a 5G ground station, or maybe via a sat reflector back to a ground 5G base station, by using a 5G protocol. This would then talk to a satellite on GEO, but not with a 5G protocol, but with an IP-over-Ethernet radio or optical link. The GEO sat would then forward that to a Lunar orbitter, again not using 5G protocols.  It would then land on a Moon 5G base station.  That Moon 5G base station would use a 5G protocol to talk to  5G terminals on the Moon. This IP-over-Ethernet for ground-to-GEO-to-LunarOrbitter would maybe involve CCSDS link layer, or maybe an SDA link layer. A complete 3GPP architecture for 5G Earth-Moon would not be 5G, but 6G, because it is too late for 5G.    The architecture would be completely rewritten at 3GPP to acommodate that.
