1. I received 2 messages at the same time: that I've hit 80% of my data limit, and that I hit 100% of my data limit. So now I have no more data for 18 days and I was not warned.

2. I paid for a new plan and was under the impression it would start ASAP as I need mobile data for work, I work as a carer for disabled children. The new plan has not been activated, it says I now have unlimited data but it's not working.

3. It says my next bill is now for £72.99, when I've been paying £21.50 per month for 100 GB data for the last 12 months, and the new plan I asked for was £22.50 per month for unlimited data. Where has this extra £50 come from?!

I hope to hear back soon, like I said I need mobile data for Monday when I am back at work. I hope someone gets back to me or I'll have to try and scrape a new plan from another company, which is very long for me to do.

Hi @Carlovacirca,

We're sorry to hear about your experience. We appreciate how important it is to have mobile data, especially when you rely on it for work.

Regarding the 80% and 100% data notifications, these alerts are triggered based on your usage. If a large amount of data is being used in a short space of time, it's possible for both messages to be sent almost simultaneously. To help reduce data usage, we'd recommend checking which apps are using the most data in your phone's settings, enabling Wi-Fi where possible, turning off background app refresh, and disabling automatic app updates over mobile data.
When you change your plan, you don't receive the full allowance immediately. Instead, you're given a pro-rated allowance to cover the remainder of your current billing period. Your full unlimited data allowance will be available from your next billing date, when your new monthly allowance refreshes.
The higher bill could be because you had a bill cap in place before changing your plan. Once your included data was used, any additional chargeable usage may have been taken from your bill cap, which can increase the amount shown on your next bill. To prevent this happening again, you can set your bill cap to £0.00 by:

Logging into the iD Mobile app or My Account online.
Going to Bills.
Selecting Manage Bill Cap.
Setting the bill cap to £0.00.

If you need more data before your next billing date, you can purchase a data add-on by:

Logging into the iD Mobile app or My Account online.
Going to Add-ons.
Selecting the data add-on you'd like to purchase and following the on-screen instructions.

We hope this helps explain what's happened, and we're sorry for the inconvenience.

Regards,

Gemma M
