HELLO LADS - listen...... I have iPad Air 2 and have an extra Apple SIM - activated it under T-Mobile and it WORKS on my iPhone 5. The new development is that you can sign up for any data plan OR enjoy the free T-Mobile 200mb option "for life" .... so yes, the new development is that Google Hangouts (with Google Voice Number) can be used under the data, and at 35mb per HOUR VOICE CALLS in Hangouts gives you around 400 minutes FREE CALLS for the 200mb free plan - what's apps, iMessages & Hangouts SMS are KB's and can send loads for FREE...... Google Hangouts in iOS for both iPad and iPhone is a much better experience than that of ANDROID...... can you believe it!!!! so there.... that's the update on this thread..... this has been possible since Hangouts launch in March 2015..... so everyone is 1 year late to the party!!!!
[doublepost=1458839240][/doublepost]one more thing... the quality of the voice calls in hangouts is better than any cell phone network as cell phone network calls uses legacy tech from the 80's.... the carriers have not upgraded to LTE properly (data voice, which was promised) and the codec used by hangouts leads to HD quality voice.... which is the same codec as the super expensive CISCO IP phones in everyone's office desks ....... happy calling!!!!! if you need an Apple SIM, pop over to an Apple Store, pay 5 bux, activate it in somebody's iPad AIR 2..... then swap it to your old iPhone 5's gathering dust..... and voila !!!
