Sim cards -- explain it to me like I'm 4 years old :-)

I've only recently got an iPhone and I'm pretty clueless, so please bear with me. We have an iPhone4 and an iPhone4s, both purchased in Hong Kong and our current service is through 3 (Hong Kong). We will be in Ireland for a week and want to be able to make calls to local number and access the internet.

What kind of sim card do I need? Where can I buy it (we arrive in Dublin in 2 days)? How much do they cost? Do I just take out my Hong Kong sim & insert the Irish sim? Any need to activate the card or will it be fully functional once it put it in?

And what happens if someone calls or texts my Hong Kong number, once I switch out my Hong Kong sim card for the Irish sim card? Can they leave a voicemail msg, which I can retrieve once I put the Hong Kong sim back in?

Thanks!

Pop into Vodaphone or any mobile shop when you arrive and they will look after you

I am not sure that iPhones can be unlocked to accept "foreign" sim cards but your provider should be able to help on that score. Meteor or 3 would be my choice for data but Tesco mobile definitely for calls and texts.

There is no nned to change any sim cards. You are a 3 customer and can use the 3 network here in Ireland, it's called roaming. Check with 3 HK before you leave. …three.ie/roaming/…three-like-home

What kind of sim card do I need?

- You will need micro sims or you will need to get a regular sim "cut down" to fit, there are tutorials online which show you how to do this.

Where can I buy it (we arrive in Dublin in 2 days)?

- You can purchase your sim from any of the phone companies, there are many through out the city. The Carphone Warehouse will also have most sims with the exception of Tesco I think. You need to decide what network is best for you. (Tony has given you advice on this above)

How much do they cost?

- To the best of my knowledge most sims are free provided that you put at least €10 credit onto it, which you will need to use the phone anyway.

Do I just take out my Hong Kong sim & insert the Irish sim?

- Provided that your phone is "unlocked" you can insert any sim and it should work. Phone companies usually lock the sim to their network as they subsidize the price of the phone. I'm not familiar with the regulations in Hong Kong, call your phone company (who you bought the phone though) and ask them if your phone needs to be unlocked.

Any need to activate the card or will it be fully functional once it put it in?

- No need to activate, it will work when you put it in. You will need to top it up with credit to make calls, texts and use data.

And what happens if someone calls or texts my Hong Kong number, once I switch out my Hong Kong sim card for the Irish sim card? Can they leave a voicemail msg, which I can retrieve once I put the Hong Kong sim back in?

- A question for your own phone company I think. I read somewhere that you have three days within which to pick up text messages made to an inactive sim but not sure about voice messages.
