When I trade while traveling and can't find a wi-fi hot spot for my laptop, I use Verizon's prepaid mi-fi plans. So I'm not committed to a monthly/yearly plan, and Verizon's network is usually decent no matter where I'm at.
I live in Miami Fl, and I need a backup plan just in case.. I am using Speedytradingservers (reliable VPS), as well. I can connect from home, iPad, Wifi, 4G. When I travel, I use them but just to monitor the closing of few last swing trades on target or stop, if necessary. Hope this help.
Teamviewer remote desktop, I don't know whether we can control computer at home using IPhone or ipad, I think as trader if having less time to forex monitoring they can trying as swing trader which making target for medium term, but if they have mobile device platform currenty some broker already use metatarder for android, they can making trades anyhwere and everyhwre as long as can login account
VPN will be also useful for establishing secure connections with a remote computer network. Today, it’s commonly known as the most convenient tool for bypassing geo-restrictions by appointing required ip addresses, and increasing level of privacy online https://www.bestvpnrating.com/beginner-guide-internet-privacy. But you can also access your home net from anywhere you want throught the installed VPN connection. Anyway, I have no doubt that VPNs is a must have for modern internet users regardless its designated use.
