I recently bought some NFC tags and have been experimenting with them a bit. I noticed that through the NFC Task Launcher app, there is no option to include a 4G toggle on an NFC tag. I really want to have this since when I'm at work all day, the only thing my phone is doing is receiving emails, so 4G is a waste for me. When I leave I want to be able to turn it back on (along with other "leaving work" tasks I've predetermined). I've heard a bit about tasker, could that be a potential solution? I've been hesitant since it costs $5+ and I don't know if I'd have any use for it. If it can program a 4G toggle, what other things can it help do in conjunction with NFC that makes it worthwhile to buy and tackle the supposed learning curve? Thanks for the help!
