Virtual mail (as of snail mail)

 So, you plan a year traveling or whatever. Don't have or don't want to have a residence. What do you do with your mail for tax, credit cards, etc purposes. First option is to ask a friend/family. Probably what I'll do. Second use one of these services (about $200/year):

Elderly emergency monitor anywhere anytime

My mom saw one of those services that they offer you a watch (and a nice bill) so that it can call someone in case of emergency. Here is a short listing of this and alternative methods. By no means the list is exhaustive but tries to at least point to the different categories.

Starting from the simplest:

1. Enable your smartphone to make an emergency call. For Android, you can add up to 3 contacts, and the phone will send pictures/audio and your location. All by simply pressing the power button 5 times consecutively...
2. If you are afraid that mom is not going to have the phone really in reach in case of an emergency, a watch that connects through Bluetooth with that phone may come handy: 
1. Most of the traditional smartwatches should be able to do that.
2. If you look for something simpler, without all the other functionality of a smartwatch, just check online for "emergency watch for elderly". 
3. If your mom has some mental illness which could result on she not carrying her phone around, a smart watch with cell phone capability will be the best. Even if she doesn't call you may be able to find her location. The issue with this option is that you obviously need another SIM and it is kind of redundant if your mom really carries the phone around. Examples: 
1. As with the previous functionality, you can just get a nice smart watch. See a review of few of them here. Examples:
1. TicWatch looks very nice.
2. Apple Watch It looks like first it calls emergency services and then the contacts.
3. Samsung gear (and I guess other Android phones) will do something similar to the Android phone case described in #1.
2. You can also try to find narrow functionality (and cheaper) ones by doing a similar search to #2, but make sure you read the reviews. A lot of those watches seem to have issues with the connectivity to the cellular network, durability... Examples:
1. Laxcido and KKBear which actually seem to be rebranded products of the same thing.
4. Finally get the same watch with a service that will take care of you in case of emergency. The monthly fee may be too much specially if mom can simply call you... There are few services out there but the whole point of this post was to try to save the monthly fee.

Cheers!
