If you are a Zero1 user and wanted voice roaming (and SMS), you would need to swap the SIM cards (those on the original $19.00 / $29.90 plans. Once you have swapped to the new SIM card, you original bill will be prorated and the new bill will begin on the date of activation of the new SIM card.
In the past, you get 1 Mbps consistently after the first 3 GB is consumed. It seems that the new plan (new SIM with roaming) no longer provides 1 Mbps after the first 10 GB is consumed.
In our tests running speedtest, it seems that the speed has dropped to 512 Kbps and sometimes as low as 384 Kbps. This is a bit on the low as most videos are not watchable on youtube at 360p. Audio streaming is still all right as there the bandwidth consumed is much lesser than video.
Are you experiencing the same issue ? If you are on the old plan, will you swap to the new SIM for voice roaming ?
