The biggest problem is MMS. Some carriers and ROMs, like ATT, convert long SMS to MMS. Years ago the love of my life broke up with me. A few weeks later she sent me a long text wanting to get back together, but I never received it because she sent it to my google voice number and it was longer than 450 characters (3 text messages). She used ATT and it converted it to MMS. Wasn't even notified it was sent, she thought I had moved on and was ignoring her, and that was it.
Does anyone know how reliable Google voice calling in hangouts is? Could it effectively replace a cellular plan?
