The six preset amounts on our form — AED 20, 50, 75, 100, 150 and 200 — are not arbitrary. Each one answers a different question about how a prepaid line is being used, and picking the wrong one either leaves you topping up again in two days or parks money on a line you barely use.
Start from how the line is used, not from the balance
The most common mistake is topping up to whatever round number feels comfortable. A more useful question is what the line is for. A second phone that receives occasional calls and nothing else does not need the same treatment as a line carrying video calls and tethering all month.
Three rough profiles cover most cases. A standby line, used for calls and messages a few times a week, runs happily on the smaller presets. A main line with a modest data bundle sits in the middle. A line doing real data work — streaming, navigation, tethering a laptop — belongs at the top of the range.
The small presets: AED 20 and AED 50
AED 20 is a patch, not a plan. It exists for the moment credit runs out mid-conversation or just before a call you need to make. It buys enough to finish what you were doing and get through the next day or two.
AED 50 is where most entry-level bundles land, which makes it the sensible default for a line used mainly for calls and messaging. It is the most frequently chosen preset, and for a standby line it is usually the right answer.
The middle: AED 75 and AED 100
AED 75 is the awkward-bundle preset. Bundle prices do not always fall on round numbers, and when the one you want costs more than the smaller presets cover but less than a hundred, this is the figure that fits without overshooting.
AED 100 is the month-at-a-time choice. For a main line with a normal mixture of calls and data, it generally covers a billing month without a second top-up, which has a practical benefit beyond the money: one less thing to remember.
The large presets: AED 150 and AED 200
These are for heavier use and for people who would rather not think about the line again for several weeks. If you tether a laptop, make long international calls or run data-hungry apps, the smaller amounts will have you back on this form before the month is out.
There is a second reason to choose them that has nothing to do with data: each request carries a service fee. Two AED 100 top-ups cost more in fees than one AED 200 top-up. If you know the line will need the credit anyway, consolidating is cheaper.
When none of them fits
Pick Other and type the figure. Custom amounts are accepted from AED 5 to AED 1,000, which exists precisely for the bundle that costs AED 65 or AED 115. The desk works with the number you give rather than nudging you to the nearest preset.
A note on topping up too much
Credit on a prepaid line is not lost by being unused, but it is not doing anything for you either, and validity rules are set by the operator rather than by us. Topping up AED 200 on a line you use twice a month achieves nothing that AED 50 would not. Match the amount to the use.
