I bought powertel dongle for $20, their sim card for $2 and paid $35 for a month subscription. The pretty girl at their front desk at Joina city assured me that my location was 400 metres from their base station in Sunridge near westgate and that i will have flow-less internet connectivity. It has been 21 days now since i parted way with $59 but i have not yet used even 100mb of this internet. It wont just connect. I took the dongle to highfields, Msasa, even CBD, it was all waste of time. Sometime it connects but opens nothing, even local websites. I have never seen such atrocious service. I went back to return the dongle and their sim to get a refund and the guy i met declared that they have fixed my 'issue' only for it to turn up as a pile of lies. Have since met many many other people who have been robbed by this powertel. The only people getting a bit of service are those using the ealier version of sim-less dongle.
