Network Usage Tips
mountainous/remote areas
In remote mountainous areas and deep within national parks, signals may weaken, so it is advisable to download offline maps in advance. AT&T's coverage has exceeded 2.91 million square miles, but there are still blind spots.
Underground space
The subway and tunnels may temporarily switch to 3G networks, with 5G/4G connections automatically restored upon exiting the tunnels. Transportation hubs are key areas for 5G coverage.
Indoor high-density areas
In high-rise buildings or basements, staying near windows can improve signal reception. Some historic buildings may affect network quality.
Price evaluation
The U.S. has extensive mobile network coverage, with AT&T 5G already reaching 290 million people and 42 cities offering enhanced capacity. Compared to other countries, eSIM prices are relatively moderate. It is recommended to choose a suitable plan based on travel duration and actual data needs, while group travelers may consider shared data plans for better cost-effectiveness.
