The roaming location of Samsung I9000 mobile phone is suddenly difficult to access the Internet? (It turned out to be usable)

The main reason is the quality of the network connection. Are you using a mobile card? Similar problems will occur when mobile cards load programs that consume relatively large amounts of traffic because the mobile network speed is not high enough. The China Unicom card has no roaming nationwide, which is very easy to use. I also used a mobile card in college, and later switched to China Unicom, and the Internet speed is very fast.
