Ovivo Mobile shuts down

Ovivo Mobile, the UK MVNO has just shut down. The Ovivo website is giving the announcement and their customers the option to get their PAC code.
The operator's unique offering was the £0 a month sim card (250 minutes, 250 texts and 500mb data) funded by mobile advertising.

Here is the announcement from the Ovivo website:

Dear OVIVO Customers,
We are very sad to announce that for reasons beyond our control, OVIVO Mobile is closing down on the evening of Wednesday 19th March 2014.
We'd like to thank each and every one of you for your support and friendship over the last two years.
To keep your OVIVO number, just fill out this form, and we’ll send you your PAC code.

PAC code request form

To request a PAC code please complete the form below. There is no need to request a PAC code if you do not wish to keep your number. We will arrange for your PAC code to arrive as quickly as possible but there is a high demand for this service.

I'm quite annoyed. Just last week I purchased a SIM card from Ovivo for £20. The SIM card was delivered today and can't be activated.
Not happening. Not happy.
If you too are an annoyed Ovivo customer, feel free to vent your anger and frustration in the comment section below.

Goodbye Virgin Media Mobile

Today I'm getting a PAC code from Virgin Media Mobile and transferring my number to another network provider. The reason for this is the changes Virgin Media Mobile made to their Pay As You Go Big Data & Texts tariff and the reduction of the data allowance on the tariff.
The "Unlimited" data allowance with every £10 topup is gone, replaced  by a 1GB data limit. This isn't enough on the device I use that number in, as I stream podcasts while on the go to it.

I'll be switching to Three UK who offer 300 minutes, 3000 texts and All You Can Eat Data for £15 per month. It is slightly more expensive but I have had good experience with Three UK with my contract SIM cards and their data service in Edinburgh is excellent.
Hello again!
So long Virgin Media Mobile. I hope to see you change your tariffs again. If the changes are good I might be back, but for now I'm off to Three.

As usual, feel free to leave comments and/or questions below.
