Sprint is likely working on towers in your area.

Sprint has been "working on towers" in my area for over a year. Every time I go into the Sprint stores to ask when LTE will be here its always the same answer: 'Well they are actually working on upgrading the towers right now, so if you are experiencing issues with data connectivity or slow speeds thats probably why. They expect to have LTE fully up and running in 1-2 months'. And as of today, still no LTE. And 3G speeds that are so slow it wont even register on a speed test.
Click on the link and read the section about 8T8R radios. So basically before Sprint brings LTE to all of its customers they started introducing Spark in select areas. Then also before completing their LTE rollout they will be upgrading the Spark towers. Even after LTE is installed it consistently tests the slowest of all 4 major carriers. And as more people buy phones that are LTE/Spark compatible, it will only get worse.
So yes it is good to be patient. But Sprint's upgrades and improvements are very slow coming so don't hold your breath.
