Note: Fasttech is shipping from China, import customs and tax will apply for EU.
For each Twizy you'll need:
Universal GPS Antenna (SMA Connector)
•

If you want to avoid having two antennas: There are combi antennas integrating GSM & GPS
available (e.g. "shark fin antenna"). If you test one of these, please report your results :-). Both
antenna connectors are SMA, an active GPS antenna needs to run on 3 V.

If you want to do OVMS development and/or debugging, a serial interface or serial to USB adapter
will be needed.

SIM card

You'll need a standard size SIM card with a data plan. The Twizy module will normally need about
1-10 MB of data per month, depending on your driving and GPS logging. Data though will be sent
in small and infrequent packets, so be aware of providers rounding up prepaid data transfers (like
Congstar.de) or book some minimal flat rate. Also, mobile GPRS coverage and stability depends
on the network; for Germany, D1 (T-Mobile) offers best coverage and stability, followed by D2
(Vodafone). E-Plus is usable in urban areas, O2 is not recommended.
Some pointers for Germany (conditions may have changed!):
T-Mobile "Xtra Call" + "Xtra Flat Daten": D1, best coverage, flat rate required, limit 50 MB
