I thought simba gives grace period 21 days after your renewal? I renew online via shopee on the 20th. my new expiry for data is 10 days instead of 30 days. A bit smelly.
Are you currently using
$10 SIMBA 100GB (50GB+50GB) postpaid plan?
If yes, you need to know that during the 21 days grace period, you can still:
(a) Receive incoming calls & incoming SMS.
(b) Access mobile data at a limited speed of 192Kbps.
That means during the 21 days grace period, someone can still call you; AND you can still access Internet on your phone at (a throttled/limited) speed of 192Kbps.
Since both voice (incoming calls) & mobile data (192Kbps) services -- are still rendered to you during the grace period --
thus the grace period will be considered part of your 30 days SIMBA billing cycle.
You can refer to this
PDF file on SIMBA Web site for details on the $10 SIMBA postpaid plan.
In the above PDF file, you can find the following:
"Unsuccessful payment for plan renewal will result in a reversion to a Basic Plan which includes only Basic Data Services (192Kbps), incoming calls and SMS."

Of course, alternatively, you can consider using Singtel/M1/Starhub prepaid.
If you use Singtel/M1/Starhub prepaid, there is no requirement to buy any data or voice plan on a monthly basis -- i.e. you can choose to buy any data or voice plan -- only as & when you need.
If you use Singtel/M1/Starhub prepaid -- any data or voice plan you buy, the valdity period will start on the DAY you buy the plan -- regardless how long ago any plan you previously bought has expired.
