Differences from Roaming

Roaming is simple and convenient, although its cost and transmission rates do not match those of WiFi routers.

Roaming is a connection method made using your smart phone.

It is convenient because you do not need to replace your SIM card or carry a WiFi router with you, but it’s very expensive. You must be careful not to connect with the wrong telecommunications carrier or you will be billed with a hefty fee. Also, in many cases, transmission rates in high traffic areas slow down so much that you can’t use the internet at all.
