Hello! Obviously, I know nothing about modems. I recently purchased a Globe at Home Prepaid Wifi [I travel often]. It came with a ZLT P25 modem. I would like to get another as a backup at work since our DSL is from the devil there. I would like to get an outdoor modem so I can get a better signal. So far I've been advised to purchase a Comfast EW-71 or Comfast EW-72 or a Comfast CF-E7 modem. The three friends who advised me have never used these so am hesitant to invest in a modem that will end up in storage. Any suggestions? I will be using a Globe LTE Sim. Thank you so much for your help.
