Sometimes when using mobile data on our mobile phones, we run out of our monthly data allowance. Once we run out of our allocated allowance, we are allowed to use mobile data but at a different rate. That is where data overage comes in. Let us dive deeper into this topic to answer some of the key questions.
What does data overage mean?
Data overage is the additional MegaBytes (MB) or GigaBytes(GB) of data you consume after having used up your monthly data allowance that you get as part of your pay monthly mobile plan. So, for example, if you get 10 GB of data in your monthly allowance and you finish it all before the end of the month, then any additional data you use on top of this 10 GB will be your data overage, and your mobile operator will charge you for that on a per MB basis.
What happens if you go over your mobile data allowance?
If you go over your monthly mobile data allowance, your mobile operator can charge you according to their out of bundle charges specified in their pricing plans. For mobile operators in the UK, e.g. Vodafone UK or EE, you can go to their website, look under “Terms and Conditions”, and you are likely to find price plans for different tariffs. These tariffs contain information on out-of-bundle charges. For example, you can find out what rate is used for each MB of out-of-bundle data for your tariff. The other, better option is to check directly with the operator if you find the detailed price plans hard to comprehend. Some mobile operators may choose to throttle your speed, e.g. maximum speed of 100 kbps, until your monthly allowance gets renewed at the end of your monthly billing cycle. This is where spend-cap becomes very useful, which allows you to set a limit on the out of bundle charges your mobile operator can charge you. So, for example, if you set your spend cap limit to £0, then as soon as you exceed your monthly data allowance, your operator would put a stop to your data consumption (or throttle depending on the operator’s policy) until the next billing cycle.
If in any given month, you end up using all your allocated data allowance before the end of the month, you may be left with two choices:
- Stop using mobile data for the rest of the month and rely solely on WiFi for any data sessions in that month
- Or, just purchase an add-on (also known as bolt-on) from your operator to have some additional data for the rest of the month
If you choose option # 2, that will be more or less straightforward as long as your mobile operator notifies you in good time so you can purchase additional data without any downtime.
If you are more inclined towards option # 1, then there may be some further scenarios. Some mobile operators make it easier by simply stopping your mobile data usage once you have reached your limits and present you with options on what to do next. But some operators don’t do this by default and let you decide whether you want to stop using any additional data through data capping. If your operator doesn’t stop your data usage once you have reached your limits and don’t have data capping, you will likely go over your data limit, which will incur data overage charges. Mobile operators charge for data overage at different rates depending on each operator as well as your tariff. As a user of mobile services, it is a good idea to be aware of these charges to avoid a bill shock.
What uses up data on your phone?
If your mobile phone is not connected to a WiFi network, then all services that require internet, e.g. web browsing on the phone, using Facebook, watching YouTube, using WhatsApp, sending iMessages, creating mobile hotspots etc. will be subject to mobile data consumption. It means all of these services will consume your mobile data. The exception is if your mobile operator has zero-rated any of these services for you, e.g. if all WhatsApp calls are included in your tariff. In addition, many apps on mobile phones usually require frequent updates that are data-intensive. Unless you have set up your phone to do such updates on WiFi, the updates can consume your mobile data.
How do you avoid data overage charges?
The best way to avoid data overage charges is to be proactive about your data plan. It doesn’t mean that you should keep counting every single MB or GB of data, but you can make use of the utilities that mobile operators already provide. Two such utilities are data cap, and spend cap can allow you to set limits on your consumption. Data cap allows you to set a limit on the maximum monthly mobile data allowance, and as soon as you exceed that limit, your mobile data will stop. Of course, you will still be able to use WiFi data. The other option is to set a spend cap that allows you to put a monetary limit on the out of bundle charges you allow your mobile operator to charge you if you exceed your monthly allowance. If you set the spend cap to zero (e.g. £0 or $0 or €0 or whatever currency is relevant), then your mobile operator will stop that service for you until the monthly allowance renews.
