Choosing an ISP is not always an easy task. There are over 70 different providers in Houston each offering slightly different pricing and features.
Some providers are local,others are regional, and still others are national.
This may be important if you travel. Local providers typically will have fewer users resulting in fewer busy signals, and sometimes a faster overall connection. Note that the ISP list does not currently differentiate between local, regional, and national providers. Hopefully, this will be one the next additions. Well first you need to decide on what your features are most important to you.
