Cellular carriers don’t have more bandwidth, usually they have a lot less, they just use it more efficiently and reuse that same bandwdith across many cells. Something like meshtastic is great but without centralised tracking of user equipment you cant handover between cells without dropping traffic. Meshtastic uses much larger bands less efficiently.
“Less efficient” is quite a misnomer here, since the meshtastic network mainly has to work around the regulations, which leaves it only small timeframes for transmitting. When such a project can only transmit for a few minutes per hour, then naturally it has way less bandwidth overall
