Change to mySIM 3 40 if you need the handset subsidy. Have to pay $21.40 downgrade fee tho, valid only if your handset contract is over.
mySIM 3 40 will reduce your main line by $2, SurfShare change to mySIM S will dlreduce charge by $0.84 per line.
Data bundle increase from 3.98GB to 15.00GB now.
Thanks!
But after checking w/ M1, issue was that Free Caller ID is only for main line.
In my case, if I take mySIM 3 20 (aiyo, the name hor....

), it'll be
$20 (free caller id) + $12 (sub-line 1) + $5 (sub-line 1 caller id) + $12 (sub-line 2) + $5 (sub-line 2 caller id) = $54
Probably will go for mySIM 3 20 + 2 x Circles $0 plans:
$20 + $10 (Circles $0 + $10 topup cos my mum wants to talk on phone) + $0 (Circles $0) = $30
Hopefully no sudden extra unforeseen charges. One thing about no contract: the company can also change terms as and when they want.....double-edged sword....
