I'm amazed so few people are asking this sort of question about their ipads. There is a ton of information on the internet about unlocking iphones (a lot of it just plain wrong) but almost nothing about ipads. Why not?
Even if Sprint agreed to unlock your device (which they won't), you could not use it on an ATT cellular data plan network. Sprint is CDMA, ATT is GMS (same as cell phones). They are not compatible systems. Sorry, but your only options at present seem to be to use your ipad on WIFI, trade it in if you can, or sell it on
ebay.
I was given a Sprint ipad as a gift. I've been trying to get it unlocked so I can add it to my Verizon Share Everything Plan @ $10 per month instead of paying $35 dollars per month for the Sprint cellular data plan. I've used the Sprint plan and got very spotty LTE and even poor 3G. Sometimes nothing at all would load. This in Chicago, not the Rocky Mountains, but I do travel a fair bit. Yesterday I cancelled my Sprint cellular data plan.
Because Sprint and Verizon are CDMA, I thought it might be possible to make a switch. Even though I thought I might not get access to the Verizon LTE network, I figured the service couldn't be worse than I was getting with Sprint.
No one in the Sprint store could answer my questions or knew who should ask. I called Sprint tech support, supplied the MEID number and explained my problem. The guy seemed very helpful and I thought it had been sorted out. Wrong.
Today I was told by an assistant in an Apple store that the Sprint ipads won't work on the Verizon network. Even though both are CDMA they use different chips. In other words, the hardware is different. They can't be "unlocked". I'm now researching whether this is true, which means hours of phone calls to the tech support people at Apple, Sprint and Verizon. I'm even fielding questions to various computer computational wizards I happen to have access to.
Unlike iphones that are sold by cell phone companies at a subsidized price under a 2 years contract, ipads are sold to the customer at full price, no contract.
Why are consumers falling for this scam of ipads being locked to only one cell phone company? If the Apple store assistant is correct, why is Apple making a different model for each company, instead of one CMDA model (Sprint and Verizon) and one GMS model (ATT and Tmobile)? Why is it so hard to get information about this, and why are consumers silent about it?
BTW, a few weeks ago I traveled to Australia with my CDMA Sprint ipad 4, popped out the SIM and replaced it with a SIM from a local GMS carrier. It worked a treat. I don't expect to be able to switch between CDMA and GMS in the U.S. But this problem of devices locked to only one carrier is unique to the United States. Why?
