It’s something like a mini iPhone that can’t make phone calls – but FaceTime video chats – and only receives data over Wi-Fi. This means you don’t have to pay for a data plan, but you can’t use it everywhere you would use an iPhone.
Question: Q: Can you get a data plan on an iPod touch?
All you can do is buy a credit card sized device from a phone carrier that has a cellular data connection and which acts as a WiFi hotspot for the iPod to connect to.
You can make and receive calls on your iPod touch by transferring calls through your iPhone using Wi-Fi Calling (iOS 9 or later required). Note: Cellular charges may apply. WiFi calling is not available with all providers.
If you have a Bluetooth hotspot enabled on another device, you can connect iPod to the Internet via Bluetooth.
Like the previous model, the new iPod Touch has a familiar iPhone-like design, complete with a touchscreen. But unlike the iPhone you can’t plug in your carrier’s SIM card and use it to make calls.
All answers. If you want to use cellular service, you need an iPhone. You could buy a wireless hotspot like a MiFi and your iPod would see it as a Wi-Fi network.
