O2 customers will get just 87p compensation each for almost 24-hour 4G data crash

MILLIONS of pay monthly O2 customers affected by this week's outage will get two day's worth of use for free - but this could amount to as little as just 87p for some.

O2 has confirmed that pay monthly customers - including small business and mobile broadband users - will be credited with the equivalent cost of two day's worth of their airtime plan.

It comes after 25million O2 customers were left without data for nearly 24 hours, while some couldn't send text messages this morning.

But affected customers may get back less than £1 and some aren't happy about it.

If your mobile plan is £13 a month, for example - which is reportedly O2's cheapest airtime plane - as there are 31 days in December, you'd get back just 84p.

Pay £20 month, and you'd get around £1.40.

O2 says it will notify PAYG customers when these deals will be available and adds that there will be no limit on the value of top-ups.

The Sun has asked if there will be a time limit for PAYG to redeem the offer and we'll update the story as soon as we hear back.

An O2 spokesperson said: "We’d once again like to thank our customers for their patience. We’re doing all we can to make sure this issue doesn’t happen again."

If you're one of the 7million people with a provider that piggybacks on O2's network, such as GiffGaff, Lycamobile, Sky Mobile, and Tesco Mobile this compensation will not apply.

Sky Mobile has already confirmed that customers will get free unlimited data tomorrow.
