How do I set up the SIM card for my One Button Phone?

Refer to your smartphone's user manual if needed.
In Germany, you should ideally use the SIM card provided. However, you can also choose a SIM card from any provider.

How do I connect my One Button Phone to the One Button Phone Server?

Which SMS command do I need to send for the APN set?

If your One Button Phone doesn't automatically connect to the One Button Phone server, you need to send an APN command. To do this, in the One Button Phone app, select "Devices" in the upper right menu and tap the settings icon (gear) for the relevant device. Then select APN settings. Simply tap your displayed SIM provider from Germany or Austria. You will be redirected to your smartphone's SMS app. The SMS containing the corresponding command will be automatically generated, and you can then send it to your One Button Phone. You will then receive a reply SMS with "APN set ok". If you are using a different provider, contact them to find out the APN settings, i.e., MCC, MNC, apnname, apnurl, user, and password. The command to be sent is structured as follows: #APN#= MCC,MNC,apnname,apnurl,user,password#

Download and install the One Button Phone app (either for Android or iOS) on your smartphone. Then register in the app with your email address and create a password.

Enter your SIM card's phone number (please use 00 instead of + as the country code) and your One Button Phone's IMEI (found on the packaging under the barcode or displayed on the screen when charging the device while it's switched off). Once connected to our server, your active One Button Phone will appear as online at the top of the app's main screen. Further instructions can be found under "Help" in the smartphone app.

How do I set the correct time?

You can set the time zone in the "Devices" menu under the settings icon (gear). For example, select GMT+1 for European winter time and GMT+2 for summer time.
