Review on 📶 Efficient Connectivity: Pantech PANTECH UML290 Verizon 4G LTE USB Air Card Modem Mobile Broadband by Greg Boulden

Pros: Have been using this type of card for about a year. Great upgrade from 3G. Lost the first card. The replacement card is of the same quality and worth replacing. Cons: Came from Revain without a SIM card and won't work without one. Verizon provides SIM cards for free. Sometimes the Verizon network drops these messages. I was told it was a random issue with Verizon's 4G network. I recommend. 2 bought. That speaks volumes.
