Buying phones without a contract is an increasing trend, with Apple and Xiaomi selling directly. Singapore phones are always unlocked by law, and as people change phones more often, the telcos' two-year contracts hold less appeal.
SingTel offers three MicroSIM-only plans: 7.2Mbps at S$37.30, 14.4Mbps at S$44.20 and 21Mbps at S$53.80 a month. All include 50GB of data capped at S$94.16, come without a dongle, and the cards are sold at all 11 SingTel shops.
On Saturday, 29th May, StarHub and M1 began selling MicroSIM cards, with SingTel following tomorrow, 1st June. It's unclear whether the telcos allow MicroSIM in MultiSIM or restrict it to data plans. Either way, scissors will do.
It seems SingTel has already begun preparing MicroSIM cards. According to forum user MorpheusV, when he signed up for SingTel's 7.2Mbps two-year contract bundled with a Huawei E5832, the salesperson told him the plan's SIM would be a MicroSIM.
