Apple's new iPhone SE is angled as an affordable entry to Apple's ecosystem, so it wouldn't hurt to have a bit more subsidy in the form of a two-year contract with Singtel.
We're not going to tell you to get a 16GB iPhone SE. That's just so wrong on so many levels. Instead, go for the 64GB version.
Also, with how much data you consume in a month, going with a Combo 2 plan that gives you 2GB of data would be advisable. Getting this plan gives you S$463 off the iPhone SE 64GB, amounting to nearly 12 months of subscription that you're paying for.
If you'd like to customise how you use your plan, allocating less messages and talk time, the Easy Mobile plan is a better choice. Considering that an iPhone SE 64GB costs S$828, you're seeing at least a subsidy of S$374. Which, honestly, is almost equivalent to a year's of subscription, which you're already paying for.
Not to forget, Singtel's recent DataX2 value-added service increases your monthly data limit by 100% for a S$5.90 per month, so that puts your mind at ease if you're ever near the data cap.
Pre-orders have started on Singtel's website till 30 March, 4pm. If you're fast, you can get your hands on the new iPhone you by 31 March, 10am.
