Cheap connectivity for your gsm project.
I tried to get a telemetry sim via the diydrones guys, but they were out! I opted for my old friend, the pay as you go t-mobile setup. I just picked up a $20 phone at walmart, then activated the sim with the iphones imei. You don’t have to do that. You can activate the new phone and update the imei later on. If you have a questionable project phone, you should activate the new cheap pay as you go phone then move the sim. You need a working phone to get the login to manage the account!
$20 phone – I got around $4 in line credit with the phone. Sometimes they include extra minutes in the deal making it even better.
Buy at least $10 for the pay as you go plan. SMS will cost $.10/each. Not the best, but nice for low investment. $10 gets you 100 messages.
However, if you find that you’re using the heck out of it, you can upgrade to a $15/month plan that gives you UNLIMITED TEXT.
