you need a lot of equipment just for SMS, the same as for calls, for 2G-3G networks : the antennas are connected to BSC-RNC then MSC (MGW for voice stream), HLR-HSS, STP, SMS center, SMS gateways (to provide access to other users for example to broadcast emergency SMS)
So the whole network. For 4G-5G, same but with IMS equipment instead of MSC and MGW and STP (picrel)
mobile phone networks don't function only with local antennas all the management is done in the core network.
