I suspect your zero1 sim account originally already got problem that why the speed it so bad. Zero1 service is bad, if you look back all the chat here. There are many ppl got problem with zero1 sim card. Some cancel and some went to zero1 office to bang table. After that speed problem are mostly solve. My zero1 account speed is good at most place in sg. I don't think is area problem. Even some area speed are no good, but if compare both speed after throttle. I can confirm speed after throttle for zero1 are many times better than myrepublic.
Any one here agree with me?
Zero1 looks like a 1 man company to me, 1 rich person sign a MNVO contract with singtel then start operate lol
Their site previously hosted at wix,but now moving to singapore amazon server and allow user to subscribe private number add-on service and IDD pay as you use.
Hopefully they get better.. as I quite satisfy with the speed after 3Gb
