UPDATE: LOOKS LIKE T-MOBILE REVERSED THIS 15% ELIMINATION!!! After being with AT&T for over 6 years, I couldn’t pass up the savings presented by T-Mobile to move over to their network. I wanted to be able to get my Mother-In-Law an iPhone with data and the far lower cost from T-Mobile allowed me to do so in addition to saving money all around. That was with the assumptions of the ETF promo and the 15% discount that T-Mobile has been giving to employees at my company for years. I had a 24% discount with my company on AT&T as well as $10/mo credit until March 2015, but T-Mobile still came out much less per month. So just under 3 weeks ago, on March 12th, I made the switch. I had 3 unlocked iPhone 5 phones that I would be bringing over. And would just get the cheapest basic phones for my 2 kids lines. Since I had 5 lines porting over, 4 of which were still under contract until October for a total of $740.00 in ETF fees (not counting taxes on those upcoming fees), I paid a net of $195 to buy 4 cheap flip phones, the 5 starter SIM cards, and tax. Assuming that I will get the $740.00 reimbursed from T-Mobile via pre-loaded credit card, but still have to pay AT&T ~$155.00 in taxes and fees associated with the ETF charges, my planned outlay to just make the move would be a total of ~$350.00. Seems like a hefty charge to make the move even with the ETF promo, but since I’d be saving quite a bit per month vs AT&T, that would wash out before the end of the year. With the announcement that T-Mobile now will be eliminating the 15% discount, my T-Mobile plan will now go up by at least $21.00 per month. Not very happy about this. I am looking at all options, even possibly going back to AT&T. I contacted AT&T and they told me that if I port back over within 59 days of my switch from them, that I could go right back to my old plan the way it was with no activation fees and the ETF of course would be eliminated as well. I had an old plan, but to add just data for my MIL, it would cost at least $20/mo more for a lousy 300 MB/mo. I would likely switch to the AT&T Mobile Share Value Plan which would give me 10 GB/mo across 5 lines (3 iPhones plus 2 basic phones…with the option to upgrade the 2 basic phones to used iPhones). This plan is somewhat apples-to-apples compared to the T-Mobile plan I have since both lose the subsidized phone pricing (each has the option now to pay more per month by spreading out the payments). For comparison, after taxes and fees (with the 24% discount in-tact on AT&T and now a 0% discount on T-Mobile), the plans I would be looking at are as follows: T-Mobile Simple Choice Unlimited Talk and Text Plan Me: Unlimited Data (I signed up for the “old” plan on 3/12…use about 3-5 GB/mo) Wife: 3 GB Data (uses 0.5-1.0 GB/mo) MIL: 1 GB Data (using approx. 0.2 GB/mo) Son: 1 GB Data (using no data, option from basic to used iPhone) Daughter: 1 GB Data (using no data, option from basic to used iPhone) $140.00/mo pre-taxes and fees $172.24/mo TOTAL AT&T Mobile Share Value Unlimited Talk and Text Plan Me: (use about 3-5 GB/mo) Wife: (uses 0.5-1.0 GB/mo) MIL: (using approx. 0.2 GB/mo) Son: (using no data, option from basic to used iPhone) Daughter: (using no data, option from basic to used iPhone) $175.00/mo pre-taxes and fees and 24% discount $190.96/mo TOTAL ($180.96/mo until March 2015 w/$10 credit) So instead of saving almost $30/mo over the next year (and $40/mo after that), I’ll only be saving about $9 and then $19 respectively. That is a big difference!!! Especially since it would take a heck of a lot longer now to defray the “cost” of my switch in which I have already invested about $195 and am facing another $155. If I were to sell off the 4 basic flip phones for ½ of what I paid, I’d be able to recoup $60 and then be out only $135 for this mess. Sharing 10 GB data should be sufficient for our use, especially since I’m the heavy hitter. I may even just cancel the 2 kids lines in October when the contracts are fulfilled. I’d also be staying with AT&T which does have overall better coverage, though in the Chicago area and where I live, no real issues with T-Mobile which is fast as well. If I stay with T-Mobile as planned, it costs me about an extra $215 to make the move ($350 minus the assumed $135 net loss if I go back to AT&T), it now takes until October 2015 to realize any monthly savings (by looking at the monthly delta of saving $9/mo for 11 months and then $19/mo for 6 months). But it does give me truly unlimited LTE data and more than enough data for each of the other lines on the plan. Anyway, considering all of the above, and the fact that I’m really ticked about losing this substantial discount after just a few weeks of switching, which is the better option for me to stay move forward with? AT&T or T-Mobile? Is there a real risk that AT&T may pull the same and eliminate existing corporate discounts? Thanks for your patience in reading this…I have a feeling there may be several in a similar conundrum.
