Requirements

• Magic Jack requires a minimum upload speed of 128 KB/s (or kbit/s or kbps). There is no minimum requirement for download speed.
  
  

Compatible Services

• Most high-speed Internet services maintain well over the required upload speed of 128 KB/s. Even with the lowest speed package, both cable Internet and DSL meet the bandwidth requirements for Magic Jack. Wireless air cards are also compatible with Magic Jack.
  
  

Incompatible Services

• According to the Magic Jack website, dial-up Internet and satellite Internet are not recommended for use with its service. Dial-up usually cannot obtain the required upload speed; however, it is noted that some dial-up services may work. Whereas satellite is faster than dial-up, it is usually slower than cable and DSL, and may also be incapable of maintaining the required bandwidth.
