Great app – Coverage? Review

This app is great - the only thing I would add/change is that it should say what type of roaming there is (LTE/ HSPA+/3G/2G, and voice and text only), because for example, T-Mobile has only voice/data roaming in some areas, HPAA+ in some areas and LTE in some areas. That is the only area where there could be improvement.
