It didn’t take long for Verizon and Apple to get their act together, and it looks like indeed Verizon using VoLTE (Voice over LTE) instead of falling back to CDMA will happen before the end of the year. The public beta of iOS 12.1.1 is out, and has enabled this.Read More
As I was putting together the list of things I hope to see in 2016, I started thinking about what tech things really made this year work for me. I decided to take a page out of Oprah's book and jot them down. These are not all necessarily things that I found this year or even things that hit the market this year, but as I think back to 2015, they're all things that I love that helped make 2015 better.Read More
UPDATE 3/23/2016: AT&T has lifted the international calling restriction, no more need for VPN tunnels back to the US! Read more at The Verge.
For those using the latest iOS 9 beta builds on iPhone 6 or iPhone 6+, Wi-Fi calling for AT&T is now an option to enable. As has been widely report, most users cannot enable the feature. But everyone can read the "Wi-Fi Calling Trial Participation Agreement". Here are few interesting highlights:
- You have to have a Mobile Share or unlimited voice/text plan to participate. Understandable.
- Your device will only make and receive Wi-Fi calls and texts when cellular coverage is weak or unavailable. Interesting that they don't want to offload all calling to the Wi-Fi network and free up more LTE bandwidth. Better quality of service management? Shows that bandwidth isn't really that constrained.
- Wi-Fi calling is ONLY available in the US, Puerto Rico, and the US Virgin Islands. AT&T limiting this service from use while roaming internationally is a surprise for me. But shouldn't be. AT&T - limited features and protecting international calling revenue. There is an alert (below) that the user must accept before Wi-Fi calling can be enabled that states that calling details including country will be sent to the carrier. My guess? AT&T sat on Wi-Fi calling. They petitioned Apple to be able to track country of origin and call details which is now in iOS 9. And now releases the feature.
Anyone who knows me knows that I love Apple products, but they also know that I love the wireless industry. With Apple's launch of iPad Air 2, they also launched the Apple SIM. It's my time to shine!
Subscriber Identity Module (SIM) cards have been in use for years by carriers in the US like AT&T (Cingular), T-Mobile (VoiceStream), and more recently by Verizon and Sprint with the launch of LTE. Overseas SIM cards have been used even longer. Previous to Apple's launch of the Apple SIM, a SIM card was provided by the carrier for each line of service. Your identity to the network/carrier was the SIM card. You could move your SIM from device to device and your service (phone number) followed the SIM. This process won't change for many, but those buying Apple's new iPad Air 2 and iPad mini 3 will be able to take advantage of the new setup.
Apple has taken an AWESOME step and launched dynamic SIM cards. Right now in my iPad Air 2 I have an Apple SIM that has service from both Sprint and T-Mobile active at the same time. I can't be connected to both networks simultaneously, but I can easily switch between each provider with the tap of a menu item. I can also manage my account with each service provider including adding, changing, and canceling service.
There are a few things you should know about the Apple SIM & service:
- Only AT&T, T-Mobile, and Sprint are supported at this time in the US
- Outside the US support is limited to the UK provider EE
- Once you setup service on T-Mobile or Sprint, you can't setup AT&T service
- Setting up AT&T service on the Apple SIM will lock that SIM to use on AT&T's network, and will not allow you to switch to other networks without obtaining a new SIM
Apparently with no fanfare, AT&T has launched VoLTE (Voice-over-LTE) in Dallas, along with what they're calling HD voice. This service allows for fast data speeds while on a call, and as long as you're connected to someone also using HD voice on AT&T, you'll have a very clear connection. I happened to discover this when doing further reading from today's joint announcement this by AT&T and Verizon that they will support VoLTE interoperability between the two carriers in 2015.
Both of the photos were taken from my home office just a couple miles from the AT&T world headquarters in Downtown Dallas, TX.

More on the joint announcement from MacRumors:
UPDATE: 11:09 PM I placed my first VoLTE to VoLTE call with HD Voice on AT&T's network (The other calls were VoLTE to 4G or POTS.) and the quality is noticeably better. Definitely more along the lines of Skype or FaceTime Audio calls.
