Communication with your friends and family back home is another aspect of travelling you might want to consider. Your relatives back home will be very curious to know how you are dealing with your host country or any information provided to you by your treating physician. They would also be interested to know how your procedure went and whether you are experiencing any discomfort post-treatment.
So prior to travel, it would be helpful to ensure your communication device offers roaming services so you can use your cell phone abroad. If possible, speak to your mobile network provider about the availability of any international service plans, to ensure maximum savings on your communication. If this arrangement proves too costly, consider purchasing a local sim card for convenience and ease of communication.
