While you are abroad it is important to find ways to stay in touch with family and friends. They will all be anxious to hear about your experiences, and you will want to know what is happening at home. A quick phone call or e-mail can make them feel much better.
It’s important to consider that being in touch as soon as you land might not be possible. So, don’t promise that you will call as soon as you land, because then when you don’t, they’ll panic. Instead, let them know you’ll get in touch with them as soon as you can after you get settled-in. Send a quick text or email when you can to ease their nerves, until you can make that call so they can hear your voice.
Some students have said that it is helpful to set up a communication plan with family and friends so everyone will know when you are available to make a call or receive a call. With time differences, inconsistent internet access, and the many excursions and activities you will be participating in, sometimes it can be difficult for you and your family to connect. Keep in mind that you are only abroad for one term, so you will want to make the most of it and be present for every experience that you have.
One way some students have stayed in touch and shared their experiences with many friends and family is through keeping a blog. This is an excellent way to communicate as it touches many people and can be flexible with time.
Communication Apps
Smart phone apps also work very well and allow students to text and call back home with ease. Viber, Whatsapp, and FaceTime are all recommended. The most common communication tool however, is Skype, which allows for free calling from one Skype device to another or very inexpensive calling from Skype to a landline or mobile phone.
#CISabroadtip: add $5 to your Skype account before going abroad to make calling phones back home easy right from the beginning.
The country code for calling Peru is +51. If people want to call you while abroad, this website helps explain how to call different numbers in Peru. An important note is that calling a landline and cell phone are slightly different.
Cell Phones 
Experienced travelers all agree: it is best to buy a phone and SIM card in-country once you arrive. Do not bring your American phone and pay huge international fees.
You will be able to purchase a basic phone and SIM card in-country. You can then send an international text message to your family so they know your new local number. Your phone minutes and texts will be prepaid by you. You “top-up” (prepay) your phone with $5-20 at a time at many locations. Your Site Director can explain this in more detail in-country.
If you have an American phone with a SIM card, it may be possible to only buy the SIM card in-country and not need to buy a basic phone. Please contact your cell phone provider for specific instructions.
Plan on not knowing your local cell phone number until you are in-country.
