常见问题

• How do I use just the WiFi app?
• Can I hack WiFi password?
  Can a Wi‑Fi router be hacked? It's entirely possible that your router might have been hacked and you don't even know it. By using a technique called DNS (Domain Name Server) hijacking, hackers can breach the security of your home Wi‑Fi and potentially cause you a great deal of harm.
• Can you buy portable WiFi?
  If you have a specific cell or internet provider, you can access private WiFi hotspots that offer premium prepaid internet access that's much cheaper than using mobile data, and more secure. There are some mobile WiFi devices that are geared specifically for one provider—say, for example, if you are a Verizon customer.
• Can I call just using WiFi?
  As we have mentioned above, WiFi calling is supported on both iOS and Android devices and you just have to enable the option to call via WiFi. Once it is enabled, you can make calls via WiFi when the signals are not available and it will happen automatically.
