Blynk not really suited for cellular

It seems that compatible cellular hardware is either 2G or 3G. With the sunsetting of these, most carriers are not activating new 2 or 3 G cellular modems. 4G will be around for quite a while but apparently there are not 4G modems compatible with blynk without using a wifi to router configuration. Please tell me I am wrong and suggest a 4G embedded modem. I thought the Digi XBee LTE would be a good choice but apparently it will not play well with Blynk. Please let me know.
