Wedfuly recommends WiFi as the preferred method of connectivity for your Wedding. Our recommended minimum baseline for WiFi is 5 Mbps Upload speed which you can test by going to speedtest.net.
If your WiFi fails the 5 Mbps requirement, then we suggest you look into the following options:
Up bandwidth with your ISP
Purchase a WiFi booster
If WiFi is not an option for connectivity, then we suggest you use a hotspot. Figure out what cellular provider provides the greatest coverage in your area, you are looking for 4g LTE service on your device at a minimum. Keep in mind that if you have poor cellular coverage, the hotspot will not provide greater connectivity, as it is using the same cell towers as your phone.
