Which network to pick

• Pick the most signal bars, 5G or LTE first, and avoid 3G
• Only pick names from this plan's network list above. If it says it cannot connect or shows No Service, pick another
• Still slow? Try another one, compare speeds and keep the faster
• Lost signal after moving to a new city, or back home? Turn automatic back on
