If U-mobile also don't know how to explain / ensure they can deliver on their ad promise, why you still want to sign on to them? You want to support company to cheat you/consumer?

Finally the decision is your own.

15% bonus = 15% top up bonus is pretty much self explanatory, I guess.

Reload 10 = get 11.15
Reload 30 = get 34.50
Reload 50 = get  57.50

The "more" includes:
1. Free Calls & Internet(Free calls, sms, yes. But I don't know where does the free Internet comes from)
2. Lowest 3G Data Rate
3. No Roaming Charges in Singapore

which are the 3 picture based ads on top of what you've read. A bit weird as the content placement is like of reverse logic as it took me my second read to notice that the 3 pictures above are for the text based ads that you've mentioned, but that's that.

Note: you can apply the same logic at the postpaid section and you will see that my logic tallies so it is pretty much it.

Free internet when you top up is part of the prepaid plan these days

example

RM10 top up = 10MB free, valid for 10 days

@BenSow

The UMI minutes will be used up first, even if you call another U line.

And if you've got free internet quota after topping up, this will be deducted before your UMI quota.

The bonus credit just adds to your main credit, so can be spent how you like. Unlike DG and Hotlink, the bonus credit has no validity attached with it.

now most umobile sim card come with MINI size and MICRO Cut, so just simply use that mini size or push out the micro part for micro size, for original nano size probably u need to proceed to center or order from some dealer that selling this, usually extra RM 10 charges, otherwise, consider for manual cut 

yup technically yes, but most probably they are still selling the old stocks because super slow sales for 7e on umobile sim packs.
