What if there is no mobile phone signal?
Use your home landline phone
The My SOS Family system works on your home phone - whether it's a normal corded phone or a cordless phone. So if you are using a landline phone then the My SOS Family system will work when there is no mobile signal.
Use our Amazon Alexa My SOS Family App
Alternatively we have the Alexa App within the Amazon Smart Home Category called “My SOS Family”. This allows you to use your voice to trigger an SOS alarm. As it’s based on your home Wi-Fi, the phone signal should not be a problem. Just remember that your Wi-Fi and Internet connection needs to be running and active at all times.
You will need to create a My SOS Family account. Press the red “free trial” button at the top of the website, and then link your account within the Amazon Alexa App. You can register within the Alexa App too.
Use our smartphone My SOS Family App
If have a smartphone, then we recommend using the “My SOS Family App” available from Apple App Store or Google Play Store.
With the smartphone app there are some great features like the “remote timer” function. When you turn on this feature in the App’s settings page, you start the countdown timer. We synchronise another countdown timer in your personal account on our secure servers, along with your location when it started, as our server doesn’t require a phone signal. Then that covers the issue of you having an accident when you have lost the phone signal. Customers use this when they are know they are entering and will be some time in an area where there is no phone signal. Examples could be when visiting someone who lives in a basement apartment or rural area.
If you're using a or basic mobile phone, or even a smartphone, having a phone signal is critical as that is your primary method of getting an alert out. To remember to make an emergency call, both phone manufacturers and mobile network providers allow you to call 911/112/999/0000 even when the screen is locked or you have no credit (PAYG SIMs) or poor signal and My SOS Family recommends that in a life-threatening situation that you first call 911/112/999/0000 emergency services.
Basic mobile phone
That being said there are some practical things you can do if you are worried about not having a mobile phone signal. You should check the area where you will be spending the most time using the phone that is linked to My SOS Family. Either check the phone itself or make a phone call.
Checking your local area for a mobile phone signal
The alternative is to check if your network service provider has good signal strength in the area you will use the phone the most - here is a useful resource for the UK:
Changing network provider & keeping your number
You may decide to move to a network operator that has a better signal in your area and you can retain your current mobile phone number.
To keep your mobile number and transfer it to another network, you need to request a Porting Authorisation Code (PAC) from your old provider, ask them for it when you call them to cancel your contract, and then let your new provider know the code when you start your new contract.
Roaming SIM cards
These SIM cards are exactly the same as the major network operators SIM cards. If you’ve ever taken your mobile phone abroad you may have noticed that the network operator name on your phone is one you don’t recognise. That’s because your current network operator is ROAMING in that country. Your network provider has an agreement with local providers in that country and will allow you to use their signal and make calls based on pre-agreed rates for data, voice and SMS.
In the same manner there are some providers of SIM cards called ‘Roaming SIMS’ that are not tied to one operator. Instead they search and connect to the operator with the strongest signal from where they are located. This means that they may change network operator a number of times. Their reliability is very good and they are used by medical professionals, lone workers, or they can be used for data by machines/computers that need to be on all the time.
Their downside is that can be a little more expensive than normal SIM contracts as they have to have agreements in place with each network provider to pay for their usage. Also you usually cannot keep your existing mobile phone number when changing to a roaming SIM.
Here are some roaming SIM providers:
There are many more providers of Roaming SIMs - just search online and you will find the most suitable for you.
