I have been using 930 for about six months now, on AT&T, with H+ obviously; no problems at all. I feel the speeds are enough for casual browsing. Haven't really tried streaming and heavy data tasks since I am near WiFi almost all the time. But, I would say, it will depend on your personal usage. If you solely depend on your data plan for your daily usage, then getting an LTE device would be better. However, if you use it only while traveling for, say, basic email/browsing/navigation tasks, then H+ is enough.
