— to turn on free incoming
dial *1300 (no hash) and immediately get charged 60c/day indefinitely. No activation fee.
to turn off free incoming
dial *1301, pay $1.50 deactivation free
As pay-per-use customer, we are paying 16c during Mon-Fri 8-8
Refill $10 to get 10D of free-incoming.
— mobile data
to purchase prepaid data refill (pay-per-use is extremely expensive like $2/MB)
sugg: use the existing cash credit to buy 7D data refill of 1GB ($7) or 100MB ($2).
Mobile data is a mental burden — We need to watch out for
- expiry of unused balance — You can carry over unused refill, by buying 10M for $1, extending expiration by 7D from “today:(“.
- biggest risk: balance used up –> addition usage would be pay-per-use and it wiped out waipo’s cash credit within hours. So before we leave Singapore, we need to turn off data access indefinitely.
A real concern, real mental stress, real risk. There’s no automatic turn-off of data access.
To turn on/off mobile data, call *360 and follow the instruction
To buy 7D data refill, call *100# and follow instruction.
