Once our plane takes off for Ireland, turn off your cellular data and roaming on your cell phone.  By way of example, AT&T charges $19.00/megabyte if you do not turn off your data while you are out of the US.

Viber – https://account.viber.com; choose “Create An Account” at top of page on left hand side. Viber offers free text, pics, videos to other Viber users regardless of location.  To call non-Viber users in USA from Ireland is 8 cents/min.
My suggestion would be to have people back in the US that you want to whom you want to contact, to download the Viber app to their phones and create an account. Once your account has been created all of your communication will be free as long as you are using wi-fi.

Some Facts About Viber

Using Viber while abroad

Viber lets you keep in touch with your loved ones during your travels while keeping the cost of doing so low – well, actually, free! Viber uses your data plan or Wi-Fi connection to let you make free calls to any other Viber user in the world!

Before your travels:

  • If you plan on using Viber while you are abroad, you should install and register the application before your trip. Activating Viber requires receiving an access code via SMS. To avoid roaming charges for receiving the SMS during your trip, it is best to receive it beforehand. Download Viber here.
  • Once you have created your Viber ID (your Viber ID is your phone number), you will be able to use Viber no matter where you are in the world.
  • Decide whether you would like to sign up for an international data plan through your GSM provider. These plans can make it possible to use your data plan without incurring very high roaming charges.

 


 

During your travels:

  • If you installed and registered Viber before your trip, you can use Viber without any additional steps, regardless of the phone number you are using or if you have a new SIM card.
  • If you did not install and register Viber before your trip, you can download fromhere. Viber activation requires an unique four-digit access code that is sent to you via SMS. You may need to turn roaming on in order to receive the SMS.

If you are unable to turn roaming on, follow the steps below:
  1. Start Viber setup again and apply a different phone number that can receive the SMS or automatic callback phone call, such as a local prepaid number or the number of the place you are staying.
  2. Viber will send the access code to the new number you have entered
Please note: In such cases, your Viber ID will be the number you provided and not the original number entered. This means that your friends should have this number saved under your contact in their device phone books in order to reach you on Viber. Make sure to use a trusted number for this purpose.

Will Viber still be free while I am abroad?

Viber-to-Viber calls and messages are always free, even when you are abroad.

The key to keeping your calls free while you are abroad is to always
