Vodafone sells a range of cards including the Nokia D211 that uses both GPRS capability and Wi-Fi, better known as 802.11b. The D211 allows users to take advantage of Wi-Fi hotspots when you’re in the office and switches over to GPRS when you’re out and about.
Telecom offers G-Trans, a “future-proofed” CDMA card. You can use it now on the CDMA network at 14.4kbit/s but when Telecom launches the upgrade to CDMA 1x in July it’s capable of reaching speeds much higher.
Theoretical maximum speeds for both networks are greater than 128kbit/s, but both companies stress this is highly dependent on network capacity, server loading, distance to cellsite and so on. An average of around 40–50kbit/s is expected.
Both cards are “always on”, allowing users to connect to virtual private networks or WANs as readily as if they were in the office. They retail for around $1000 each depending on the contract.
