My first letdown by Apple customer service. Historically, I have had nothing but top notch service from Apple with repairs, appointments, ordering. Recently, my iPad Air wifi/cellular started displaying “No Sim installed”. The unit has no damage or water exposure, just some rare bumps here and there from 5 years of use. I figured the contact pins or the SIM tray port were the issue, since testing different SIM cards and none being detected. Reset all network settings, etc, appears to be physical hardware issue. I called Apple and the rep said I could send it to them and pay a $249 + tax + 6.95 secure deposit. Upon receipt, their repair center was supposed to contact me with repair cost or option to return my iPad Air to me. However, I just got an email saying that Apple shipped a replacement iPad Air unit (and the $280 charge sticks). If you’re still reading this rant, this is the kicker. That original iPad Air (now “scrapped”) had an IMEI tied to my T-Mobile 200mb/month free for life account. You can google this promo, which ended in May 2017, and T-Mobile does not grandfather these accounts with new iPad devices. So basically the replacement iPad Air (different IMEI) will not work with my T-Mobile 200mb/account. I tried using this account’s nano sim with my iPad Pro 10.5” and T-Mobile rejects the lte data use on this IMEI. I called them twice and they said nothing they can do. Their system will not register any new IMEI devices on the 200mb promo account. I actually had great use of and utility on this plan. Apple rep transferred me to 2 supervisors up the chain of command. The 2nd tier supervisor said the old iPad Air has already been scrapped and unretrievable. She offered to wave the $280 service fee and for me to keep the replacement unit. I told her that’s not equitable. She said the Repair center never gave me an option or contacted me because they ASSUMED I just wanted a working device back. Just another volume transaction for the Wall Street driven Apple. Apple didn’t treat my personal legacy device as if there’s any value (sentimental or otherwise) to the customer (was running good on iOS 10.3.3 with 200mb free lte, battery still good, and my FIRST iPad). What would you ask Apple to do as reasonable compensation?
