There are Better Options Out There
This product is good in concept and poor in execution. This is an unlocked Canadian version and (per the manual) 3 way calling works differently than the US version. The manual says you must dial 3 followed by flash to create a 3 way call. However, it didn't work for me. Flash simply switches between two calls.
Other CX issues are (1) It took over 10 minutes to boot up, even after the SIM had been previously installed in the device.and (2) it takes 8-10 seconds after you finish dialing to send the call through.
If you need to stick with GSM-heritage networks (e.g. AT&T and T-Mobile) then the Netcomm seems to be a better option and our testing indicates that it supports 6-Way calling without any fuss.
Also, if using Verizon Wireless (or Verizon Wireless MVNO resellers) is an option, the Novatel T2000 works well in our testing and supports incoming DTMF well if you need to control a home answering machine to retrieve your messages.
