ALL CREDIT GOES TO GADGET88 Guide written by Nrwrit3r (me) ---- Items needed: "Dumb" phone, with the IMEI number (found in the battery casing) - This can be bought as a "go" phone from any radioshack, at&t store, walmart, ect for $30. iPhone sim information (found in general--> settings --> ICCID, write this down as you will be using the iPhone to call at&t) Access to your account for at&t ---- - Call 611 on your phone - Click 1, 0, 0 (this is the series of #s you'll type in even if you listen to the automated voice) - When you get to an at&t rep, tell them you want to switch from your iPhone 4 to a non smart phone. Also tell them you have an adaptor to make the micro sim work in your non smart phone (they will tell you it may not work, just tell them you want to do it anyway). - Give the IMEI number of the non smart phone - Give the SIM number of the iPhone (have this written down beforehand since you're on your phone) - Everything should be set. They should confirm it's been switched. - Ask for the $30 unlimited texting, email, and data phone ***for non smart phones*** If you have a plan with unlimited messaging, you will need to disable this (you can add 200 msgs temporary for $5 per line), and follow the rest of the guide. If you have it enabled you can't select this $30 non smart phone plan. You can re-enable it after you have unlimited 3g data in 2-3 hours. - After it is set, hang up. - You don't even need to turn on the non smart phone. Make a call from your iPhone. This will make the system realize you're still using it. - You will get 2 texts from At&t (within 2-3ish hours): Message 1: "At&t free msg: did you know an eligible dat plan is required for your iPhone? Call 611 or visit att.com/iPhoneplans for details." Message 2: "At&t free msg: Your iPhone requires an eligible data plan. We have added an appropriate plan and messaging pkg. Call 611 or go to att.com/iPhone plans for info" You'll also get an email saying the same thing. If you log into your account on At&t's site you'll see that you currently have the $30 plan for non smart phones for unlimited data/messaging/email selected. Wait a few hours, and it will automatically change to $30 unlimited 3g data since you have an iPhone. ^ You will get a text message (this is a 3rd message) in 2-3 hours notifying you that you have the unlimited 3g data plan. Welcome to the unlimited club If you disabled unlimited messaging, re-enable after the change has been completed. **If you have not received info of the change after 4 hours, see below** I had an issue, where although others were getting the texts and having their 3g unlimited plans activated, I was not. I got the texts saying a plan was chosen for me, but I logged in online and was still on the $30 dummy plan. I called at&t. I told them I had switched to my dumb phone, and then was switching back to my iPhone (please note I had already done all of the steps listed above, so this was my 2nd call to at&t). I told him I wanted my unlimited plan transfered back to my iPhone 4. He did it! He had to enable 200mb plan for the iPhone and then change it to unlimited, but he did it. So, if you haven't received that confirmation text, try calling at&t and telling them you're switching back to your iPhone (this is after you've called and switched to the dummy phone). ^ Try mentioning that you'd done something like this before, and the last rep had to enable the 200mb plan THEN switch you to unlimited. Haha he said a survey would be coming and asked if he got a 10/10, I said yes. I have a feeling he knew exactly what I was doing ---- ALL credit goes to gadget88 for this thread.
