Autism SpeaksWhat is AutismAsperger Syndrome. Asperger syndrome is one of several previously separate subtypes of autism that were folded into the single diagnosis autism spectrum disorder (ASD) with the publication of the DSM-5 diagnostic manual in 2013.
T-Mobile's new plan lets customers upgrade their phones whenever they want, up to three times a year. The Jump On Demand program is essentially a phone leasing program. You can trade in your borrowed phone for another one as long as you keep paying your monthly wireless bill to T-Mobile (). It's kind of like a car lease.
For example, if you're a T-Mobile user, you could use an AT&T phone on the T-Mobile network (or vice versa) so long as you put the T-Mobile phone's SIM card into the AT&T device. This is super useful if your GSM phone is broken or you want to try out a friend's phone. Keep in mind, however, that this is only true for GSM phones on the GSM network.
