I would check to see that free international texting means texting while you are located outside the US and NOT simply that texts to international numbers are free while in the US before you go wild texting on your trip.
I would say based on what I have read that the International messaging applies when you are within your normal service area.
"Llamadas y textos ilimitados para todos los dispositivos de tu cuenta. No more worries about overage charges. Send as many text, picture and video messages as you want, including international messages."
I have 2 Smart phones with 1gb data, now I understand it's doubled to 2gb data. Did the pricing go down by $10 a month with the new plans?
If you drop back down to 1 GB yes your bill will drop by $10.
key word-"send". would that mean "sending only"? And if you received int'l messages, you could get charged for that service?
Getting paranoid about these "exclusive" offers having been blindsided by a few in the past.
