You're lucky. I bet at 90% availability of 4G a lot of the negative threads would disappear and any that are loudly complaining w/ 90% are being a wee bit unrealistic. I can ride it out because I use my phone at home and work for data, and I have WiFi available at both locations. Data was down for most of yesterday and the day before and it's the 3rd complete/extended outage in my area this month. If it were not for WiFi, I'd have been screwed. Let's hope that we will all soon experience the level of service that you have!!
Did you try switching to CDMA only mode?? Because although my phone wouldn't connect to either 3G or 4G in CDMA/LTE, it connected to 3G just fine when switched to CDMA only. Why does that work? God only knows, I don't understand it. But it does work, at least for me.
Now the outages in the last month, lets say in any given month there are 3-4 days of COMPLETE outage on 4G, like this month for example. Even given that scenario, that still means 85-90% of the month it is working. Now taking into account the 1 day that I couldn't connect to any data in the last month, that's some kind of data coverage around 97% of the time.
I'm pretty satisfied with that.
