Do NOT WRITE 0 because the system will not be able to read it correctly and SMS will not be sent from your SIM card.
Kindly check the Terms of Service of your operator in order to set a concientious SMS limit (hourly/daily) and to avoid any issues related to your SIM card and mobile plan.
! ! ! Warning ! ! ! Select only the country(ies) your SMS bundle includes. Your operator may apply extra-charges.
Note: Higher prices will affect the amount of SMS sent from your SIM card. If you want to send more SMS, please keep the price in the green area.
The red squares indicate that Simcash.io was unable to send SMS from your SIM card.
After 3 attempts of sending a SMS, your SIM will be automatically paused from the system.
This might be due to 3 factors:
Try to send a manual SMS to a contact of yours and see if the SMS is delivered (and sent) or not.
Please, check your mobile offer/SMS bundle because sometimes operators give you many (or unlimited) SMS on-net (to the numbers registered under the same operator) but not off-net (to other mobile carriers).
Note that go against the Policy or the Terms of Service of your mobile operator may lead to a complete SIM blockage and suspension of Internet, SMS or calls services
To avoid any issues related to your SIM card and mobile plan/subscription, we strongly recommend:
Unfortunately, it is not possible to hide the sender's phone number.
This is not a lack of SimCash.io, it is a feature of SMS protocol worldwide (which requires a visible sender's phone number).
Remember that only OTP ("One-Time Password") or A2P ("Application-To-Person") SMS are sent, NOT SCAM or PHISHING SMS.
However, it is preferable to not reply to calls from unknown numbers or set up a SIM card only for SimCash usage (and not your personal one).
Sometimes a person complains because he has not received the code from "WhatsApp", "Facebook" or other companies/applications, but from a number which he does not know, so he might think the SMS is sent from (or to) the wrong person and he might call back.
Note that:
SMS content is liability of SimCash.io, not on the usage of your SIM card and SMS bundle.
Your mobile operator may limit or block your SIM Card if you go against its Terms of Service.
SimCash.io can not guarantee any fixed income.
SimCash.io can not guarantee the compatibility between any message or content format and any particular mobile handsets or mobile operating systems.
When you click the home button from the app, an icon should appear in the notification bar.
You can easily log out (and stop sending SMS) by clicking “Stop” from the SimCash.io notification.
If no icon appears or it disappears after some minutes, please check the following topic.
Remember that SimCash.io can send SMS only with an active Internet connection and it must be set as the default messaging app of your device.
This could depend on your device model and your Android version.
Anyway, you should check in your device settings options as "battery saving", "automatic App start" or "background App options".
For Almost All Android Devices
Generally, you do not have to do anything. If you face out some problems with background option, follow these steps: Settings -> Device Optimization -> Automatic Optimization -> Disable "Close apps to free up memory"
For Huawei and Honor devices
These devices have internal processes to free up memory automatically. To stop this optimization, follow these steps: Settings -> Battery -> Automatic App Launch -> SimCash -> Click on the blue button on the right -> Click "Okay" [then, the button should change to grey]
For Samsung (and > Android 10)
You may need to activate more advanced settings. Follow these steps: Settings -> App -> Search "SimCash" -> Battery -> Optimise battery usage -> Filter by "All" -> Search "SimCash" -> Disable the toggle [you may click also on "Mobile data" and then "Allow background data usage", also while Data saver is active]
Low-cost or other devices
If you are willing to buy a low-cost device online, take a look before buying it and check its Android version carefully, because some of them are Android 5.1, even if "Android 9" is written in product description.
