If this cannot be used on a T-Mobile iPhone 5S, why not?

Not sure if it can work on a T-mobile iPhone 5S, but it works poorly on my ATT iPhone 5. It drains the battery twice as fast when I put this on instead of allowing me extra battery life.

I don't know why. From my experience it worked for only 6 months on a iPhone 5. Maybe the iPhone 5S needs more than the I-Blason can provide.

The problem, with my iphone, that I use abroad -I live in Colombia-, is that in many occasions when I need to charge the phone, the battery blocks and won't charge unless I reconnect the device and charge it for a few seconds. Then it will woe properly an it will charge completely my iphone, but, as I said, if there is no electricity around, it will work only as a case, not as a charger. Sorry for my english and I hope this answered your question

I don't see why you could not use this with a T-Mobile iPhone, but you don't want it any way. I really wanted this case to work for me for the sake of continuing to use the lightning cable to charge the case. Though after returning two that had problems I gave it a third try with no luck. All three of the devices they sent me had issues and did not function properly. It just is not made very well and simply just does not work. I went back to Mophie and am happy with my Helium case.

It's the 20 pin connector. I bet you could find a converter tho... no personal experience trying to fit a 5s

I do not have a 5s phone so I do not know but you do need to down load app and may be cost some money .

Doesn't work on T-Mobile phones unless it is unlocked. Runs only on the simple mobile network.

Many thanks for your kind inquiry. As we know, iPhone 5S is the lightning connector, while the item is a 30 pin one. So can't be used for iPhone 5S. Any further questions, please don't hesitate to let us know. Thanks a billion.

Yes. I'm pretty sure all iPhones are the same just the carrier that changes. I happen to have my iPhone 5s with tmobile as well. :)

You can. But beware of this seller. I ordered for my 5s and they don't work..

Although the info says it can be used for the IPhone 5 I have also found that it does not support it.

I don't work on Tri State camera & neither sell iPhones but I could answer your question about T Mobile SIM. It's because T Mobile can work with any Smart Phones as long as it's unlock with GSM network compatible.

Believe you can use it on any server I've used it twice on two different occasions with T-Mobile but I don't see why you couldn't use it with any company

I don't know it is usable for T-mobile or not. I am not aware of T-mobile system. I am using the iPhone in Thailand.

Josh, it works with my 4s, so,I don't know why it would not work for the 5s.

Will not work for iPhone 5 or 5s because those use the lightning connection which is different from this one. This is for iPhone 4 and older.

It is using an illegal lightening chip, so your iPhone regardless of 5c or 5s, will not recognize it and not charge if you update to iOS 8 or higher, so if it fits it does not matter.

My understanding is that this unit was built specifically for T-Mobile to be used in a service that is no longer available, T-Mobile VOIP (you can use the service until you opt out). It probably will not work with other service providers. Since the units are no longer produced, there is a market for your unit.

My wife has the iPhone 5. I don't see why it wouldn't work on a 5s. They're the same size
