Hi there, In December 2017, I upgraded iPhone 6+ to iPhone X. I still have iPhone 6+. I will be in Italy for 45 days. Due to nature of my business, missing gmail, voice, and text - not an option. Verizon charges $10/day for international usage. TIM/Vodaphone SIM is $40/month. It seems financially prudent to purchase the SIM card for the iPhone 6+ and have all gmail, text, and voice call forwarded. Gmail is easy because it is universal. Text and voice are my concern. Questions: According to Apple website, I can set message forward via iMac message/preference/settings…. However, my iPhone 6+ is not listed because it won’t be in service until I am in Italy. By then, I can’t access my iMac. How do I accomplish this once I get the SIM card in Italy? How do I backup/sync/??? so iPhone 6+ has all the apps, messages, voice mail that I currently have on my iPhone X, prior to my departure? This way, upon arrival in Italy and new SIM card, it is closely resemblance my iPhone X. Thanks for your expertise.
