Data Roaming -cheapest way

[Saba19]

I want a plan to roam abroad inTurkey when I travel in June and again in August.

I don't want to use the Vodafone number in the UK, it is purely for travel.

Can I get a sim that will continue to work from June to August, even  when not in a phone and just add a data bundle to it in June and another in August.

Is this the cheapest way to do it? 

I'm happy to pay a minimal money charge from June till after I travel in August to keep the sim live so that I can add the bundles.

I don't want to buy a sim in Turkey as apparently it gets locked after 30 days and you can't use a Turkish sim until you pat taxes on the phone.

Please help!

Apart from using WiFi where possible, available in most cafes and hotels, there is no cheaper way when you are roaming in Turkey @Saba19 

The charges are here: Charge Checker and here: Roaming 

If your phone is unlocked you can always use a local SIM in the phone, that would work out a lot cheaper for calls, texts and data.  If you use Google, you may find some options for a local Turkey network SIM.

If you have a Vodafone PAYG SIM, you will need to add credit and make the first chargeable connection in the UK.

Thanks for your response @AnnS 

I don't want to use a local sim as that is a one time solution and won't work when we return.

It seems like buying a pay as you go sim and adding a roaming bundle before I go is the way to do it.

I think this will still work out cheaper than EE who will charge £6 a day for 500MB
