What should I do if I travel to Thailand in a few days and my mobile phone needs Internet access?

1. Buy a local calling card/network card. You can find a lot on the Internet (Tmall), most of them can only surf the Internet and can't make phone calls (some support limiting the call duration), so the signal will be really unstable.

2. Rent overseas WiFi. Now some people rent portable WiFi when they leave the country, especially those who go abroad for a long time. You can switch local networks intelligently, and you can surf the Internet directly after purchasing local traffic. There are also many ways to choose from online, but if you rent overseas portable WiFi, you need a deposit, make an appointment in advance, and it is troublesome to return the plane. Generally, it can be mailed or picked up at the airport.

3. buy portable WiFi. For people who often travel abroad or have business trips, or many people who like to travel abroad at home, you can open your own portable WiFi, and you can place an order directly online and deliver it to your home. There is no need to make an appointment, and there is a warranty service, which saves a lot of procedures such as refund and deposit. When family members travel abroad, just take them out directly, which saves a lot of trouble.

1. Wireless network refers to "wireless compatibility certification" in the field of wireless local area network, which is essentially a commercial certification and a wireless networking technology. In the past, computers were connected by network cables, while Wi-Fi was connected by radio waves. Wireless router is common, so within the effective range of radio wave coverage of this wireless router, Wi-Fi connection can be used for networking. If a wireless router is connected to an ADSL line or other Internet access line, it is also called a hotspot.

2. Wireless Internet access can be simply understood as wireless Internet access. Almost all smartphones, tablets and laptops support Wi-Fi access, which is the most widely used wireless network transmission technology today. In fact, it is to convert wired network signals into wireless signals, as introduced at the beginning, using wireless routers to receive related computers, mobile phones, tablets and so on that support its technology. If the mobile phone has Wi-Fi function, it can surf the Internet without using the mobile Unicom network when there is Wi-Fi wireless signal, thus saving the traffic fee.
