AT&T’s HD Voice and Verizon’s Advanced Calling (both LTE Voice) haven’t been deployed nation-wide because they’re so new.
For LTE Voice to work, both callers need to have new phones that support voice calls over LTE.
If you’re still reeling from the roaming charges on your phone bill in 1999, you’re not alone.
We’re all due for some up-to-date information about what roaming means for i Phones today.
It’s amazing that almost everything we do on our i Phones uses data! LTE stands for Long Term Evolution and it’s the latest and greatest in wireless data technology.
In some cases, LTE can be even faster than your Wi-Fi at home.
Nowadays, even your phone calls can use LTE to make your voice sound crystal-clear.
You’ll find Cellular Data in Settings - Cellular Data. When Cellular Data is on, you’ll see LTE in the upper left-hand corner of your i Phone. It’s the fast data connection available, unless you’re using Wi-Fi.You’ll only want to choose Data Only if you’re having trouble making phone calls with LTE. At the time of this writing, Verizon and AT&T are the only wireless carriers that use LTE for phone calls, and both of them don’t count LTE voice as part of your data plan.There are rumors that T-Mobile will add voice over LTE (or Vo LTE) to its lineup in the near future.It’s absolutely OK to turn off Cellular Data if you have a minuscule data plan or you don’t need internet when you’re not at home.When Cellular Data is off and you’re not connected to Wi-Fi, you can only use your i Phone to make phone calls and send text messages (but not i Messages, which use data).
