DOUBT: is the sim800l only 2g network? and 3g network? Alternatives?

I’m working on a project at the university, but asking the operators about the band, they give me new news, maybe some deactivate the 2g network, I have different sensors that send information through sim800L, my country is Panama, the sim800L Current are working perfectly, if these could not take the 3g network, what alternatives can you recommend?

These modules can only take 2G network. If you need 3G use SIM5320 or SIM5360.
