For pure 5G connectivity, other than Netgear I'm not sure what other vendors provide 5G portable modems, the models are Netgear Nighthawk M5/M6, both are 5G and WiFi 6 capable portable routers. Other than that almost all the ones that is on Shopee is just normal 4G WiFi 5(?) routers and/or modems with TTL changed to bypass hotspot caps
