Essentially NO. Here is the deal... if you live in downtown Dallas and try to surf during rush hour, you may not receive the highest speeds because the cell towers get crowded. Unless something similar like this happens to you, then all should be well. You should know that the major carriers may be working on the cell towers close to you that could slow you down. That usually doesn't happen, but occasionally it does. We have no control over possible network optimizations being conducted by major carriers if any of their cell towers are being updated or de-prioritized.
