No, I don't work for T-Mobile.
I mean we need to make sure it is a priority. Some of us use these iphones for business. I am like most of you and love T-Mobile and did not want to switch over to AT&T. We need to stay on them to fix this bug.
I love the internet. I come across this seemingly obscure problem (txts from weird contacts, dated in the past and the future, etc.) on my cellphone, wonder what it is, turn to the web to find out... and within 60 seconds I find this page telling me the problem is relatively widespread. Not only that, but that it pertains to unlocked IPhones using T-Mobile... like mine. Now I can assume it's not some netherworld entity trying to contact me through space and time... that's a relief

.
Then, as a bonus, I read a debate on the merits of T-Mobile vs. AT&T, a subject I have strong opinions about. It's nothing short of refreshing to see other people who went out of their way to stick with T-Mobile, like I did. Why? Because they have the best customer service hands down.
Do they have the best coverage? No. In urban areas they're as good as anyone but once in the burbs or rural... they kind of suck. Is their data network any good? Not a chance. I ended up dropping the $25 data plan (something you can't do with AT&T if you get an IPhone) once I realized it was accessible only about 1/2 the time and was painfully slow the other half. Do they have good choices of phones? Hell no. Most any of the best gadgets you'll want likely WON'T be offered by T-Mobile. Do they have the best rates? They're competitive, certainly not bargain basement though.
What they do have is integrity. They respect me as a customer enough so that when I need to call customer service I'm not left on hold for an inordinate amount of time by some flunkie manning the phones as a summer job or getting forwarded to India or the Philippines with someone rigidly working from a script like a robot.
You dial 611, enter a few menu selections (which, btw, are not designed to make you dig to discover some hidden menu path to an actual representative) and within a minute you'll get a knowledgeable, intelligent, courteous person who actually listens to what you're saying, uses their brain and earnestly works (and succeeds) in helping you. They not only do this, they do it consistently... which is no easy feat. In a few words, they give a sh&t about customer service. My bet is most of us stick with T-Mobile b/c we like to vote with our wallets.
I've gone through Verizon, Sprint and some others. For me Sprint (which I used in the 90's) was a joke when it came to customer service. If there was ever a problem, they'd nickel and dime you and be inflexible and threatening when problems arose. Verizon was almost as bad and had bad, delayed voicemail notification issues. T-Mobile throws extra minutes at you if they think you've been inconvenienced. A small gesture, but it means a lot. They treat people with respect. As a result I try to do the same with them. I feel good about giving them my money and have, over the years, signed up two additional accounts with them.
Another thing I like about T-Mobile is their call quality. Voice quality is better than any CDMA service and is sharper and clearer even than AT&T's GSM network. This goes not only for the user, but for the person on the other end... people sometimes comment how they didn't realize I was on a cellphone as the sound quality is clear and sharp. I think T-Mobile may devote more bandwidth to each call signal. Their billing is straightforward and their website is easy to navigate.
I'm with them for over 6 years without a contract. I bought an Apple unlocked Iphone from Italy (apparently Italy doesn't allow pairing of phone equipment with particular carriers) at a premium in order to stick with T-Mobile. Plus I didn't want to be forced into a two year contract with AT&T.
I agree with those who hope T-Mobile understands they should make this text message problem a relative priority. We pay monthly service charges just as anyone with a T-Mobile phone does.
I don't worry though- they'll take care of it.
They always do.
