For a mobile phone customer that does not want to commit to a year-long contract there are many different O2 30 day sim deals that are available. An O2 30 day sim plan is not going to give you the same number of calling minutes and at low costs it does not include calls to other O2 numbers or to landlines. As well, none of the 30 day O2 sim deals include internet access although it can be added on for an extra charge. All plans include unlimited text messaging.
At the low end of the price scale is the £10 plan. It gives 100 minutes of talk time but no landline or O2 to O2 calling. For £15 you receive 300 minutes of calling time, but not unlimited O2 to O2 calling or landline calls. At £20 per month, a 30 day O2 sim plan will give you 600 minutes of talk time. All plans at £20 and up also give unlimited O2 to O2 calls and unlimited landline calling.
For £25 subscribers will receive 900 minutes of talk time and this amount of talk time increases to 1200 minutes of talk time with the £30 plan. The most expensive plan is £45 and it gives unlimited talk time which can be great for anyone who does a lot of talking on their phone. Choosing which plan suits your budget is up to you but all of these plans only apply to unlocked mobile phones or phones which are active on the O2 network but are not still under an existing contract.
