Iphone 6s plus data issues

Data keeps dropping in and out, when it comes back on it says sprint for a second where it shows the lte then flashes boost 1x, back to LTE, sometimes doing this multiple times. Even when my data is kind of working I don’t get anything more than 1 bar if lte. I’m quite upset I just upgraded my phone and to the new plan for the hotspot and i can’t use either correctly. I’ve contacted boost twice of the issue, both times getting the same response and fix of dial this code and then this code. Nothing works tho. If anyone can help appreciate it really tired of this.
