I'm looking for some guidance from computer and phone tech savvy people. On Friday I'm going to Mexico for a week with my girlfriend (we are Canadian) and we both plan on leaving our cell phones at home, mainly to prevent loss or theft but also because texting and phone calls are ridiculously expensive. However, I'm taking my old Samsung S5 (loaded with 1000 songs) and a Bluetooth speaker so we can have some music and will also use it to check emails and for possible occasional internet access as the resort has WIFI. The S5 is no longer connected to a network but I'd also like to be able to check text messages with it via internet or email as my girlfriend has an almost deaf 85-year old father who primarily communicates via text, and she'll feel more comfortable if she can keep in touch with him. I've done some searches and Pushbullet and Airdroid seem to be possible solutions. Does anyone have any experience with these apps or other suitable apps, or any advice that they can share? I'm not looking for a long term solution or the ability to transfer large pics or files...I just want to be able to read or send the occasional text via WIFI on my old smart phone.
