  "account": "Many old Android phones in drawers today are 3G or even 2G phones, even if they show newer network icons. The letter next to the signal bars indicates the type of mobile data connection the phone can use. Here's what the icons mean:\n\nG: GPRS, which is very slow 2G data, and cannot handle live video streaming.\nE: EDGE, still slower than G but not fast enough for live video.\n3G/UHS/ HSPA+: These are the 3G networks, which may work for low-quality streams if the network is still available.\n4G/LTE: This is the best choice for live streaming over mobile data, but it's not always available everywhere.\n\n2G and 3G-only phones can still be good offline security cameras. They can record to the phone's own storage without needing any network connection at all. Watching the live view remotely only requires a Wi-Fi connection, not mobile data.\n\nThe short answer is: A phone limited to 2G data (G or E icon) cannot carry a live YouTube stream, while a 3G-enabled phone (3G, H, or H+) may work if 3G is still available in your area. However, a 2G or 3G-only phone can still function well as a security camera, recording to its own storage without needing any network connection.",
  "summary": "Many old Android phones in drawers today are 3G phones. Some are 4G phones that have been set to 3G or 2G years ago and never changed back. If you want to use one as a shop or home camera with a SIM card for mobile data, the network letters at the top of the screen tell you most of what you need to know. This guide is written for budget and older phones, prepaid data, and places where the mobile…",
