Frequently Asked Questions

Please read this article. You may also need to disable the "hide my number" option, otherwise iSocket cannot “see” to which number it should return a confirmation.
Sometimes a new SIM-card needs time to become activated. The operator may send settings to a new device. iSocket will accept these settings and will start to operate in normal mode. If you have not received a response after 5 minutes, please check that the SIM-card was properly activated. Read this article about prepaid cards.
Please check this webpage which specifically covers the use of SIM-cards for US customers.
Please check this webpage which specifically covers the use of SIM-cards for customers in Canada.
All current iSocket devices are 2G (GSM) 4-band devices. This means that they will work all over the world through GSM mobile networks. We are currently designing a 3G model of iSocket in addition. Please note that iSocket does not require high band data traffic for operating, because of the nature of applications where iSocket is used. For remote switching, rebooting or even temperature monitoring you actually do not require high load data traffic. There is a significant difference between the price of a 2G and a 3G module, and LTE modules cost even more. If we integrate these modules into iSocket it will change the price of the product for the final customer. The final customer would have to pay more for a product with features that actually are not required - particularly the capability to manage high band data traffic. Why do we design 3G models then? Some countries are developing modern network fast and they offer better tariffs for 3G SIM-cards. That is why we want to release a 3G model as well. The customer will have the choice to use either the 2G or the 3G model. Follow the news on our website. Like us on Facebook, Follow us on Twitter or Add us to your circles.
This is probably a misunderstanding. Many mobile operators have started promoting high band traffic 3G/LTE SIM-cards. But this is just a characteristic of their marketing. In fact most of these cards also support voice and messaging through the GSM mobile network. All you need to ask your operator is whether this card supports SMS and voice over 2G (GSM) network. In the US both T-Mobile and AT&T still retain compatibility for texting and voice over a GSM (2G) network either on their own network or through partners. You can check their coverage map on their websites. One good solution is to use a so-called roaming SIM-card. You will find different companies who sell these international SIM-cards that work over GSM mobile network in many countries. One of them is Truphone. Read more about prepaid cards on this webpage.
You may use either a French or a Belgian card. iSocket can work on roaming. It's up to you to select the cheaper solution. E.g. if you manage the device mainly from Belgium it might be cheaper to put a Belgian card into the iSocket installed in France, because an SMS from Belgium to the Belgian number could be cheaper than from Belgium to France. You must remember that iSocket will send a confirmation for the executed command. In the above case it will send from the French to the Belgian number. Remember you can always disable confirmation and that will save the credit on your card.
If your operator requires activation of the SIM card or sells cards with an enabled PIN code you first have to activate the card with your phone and/or disable PIN code, again using your phone (read more). This might be a challenge if your iSocket model has the standard size big card and your phone only accepts micro SIM. In that case we could only recommend that you visit one of your operator’s stores and ask them to activate the card and/or disable PIN usage. Alternatively, you may borrow a phone that accepts standard size SIM cards. You only need to do this once, to activate your card or/and disable the PIN code.
There are not many options if the connection is weak. The only option is to try to change the location of the unit inside the object (boat, house) and its position in relation to the floor - vertical, horizontal, perpendicular. Note, when you change location/position the unit might not pick up the network immediately. The maximum power that the mobile module gives is when it starts operating - i.e. at the moment when you power on the device. So the best way to check a new place for the unit is to switch the power off and power it on again and wait to see if it is able to log onto the network. Then send the command “STATUS” and compare the signal report in the new location/position of the unit.
Unfortunately, the device cannot work without a SIM card, which is why you won't be informed if the SIM is removed. But if you call the device you will hear a message from the operator that the person you are calling is not available. This can be treated as an indication that the SIM has been removed (of course it could also be due to a fault in the mobile network).
There are usually no operators that offer SMS’s free of charge, but there are those who do not charge a monthly fee for prepaid cards. The most important way to save is to check that airtime (credit) does not expire. E.g. if you buy a SIM card for 30 EUR and a message costs 10 cents you can use it for 300 messages. Perhaps this is enough amount of messages for you for the whole year. But if the airtime expired after 1 month, then it is not a very good deal. Airtime for some prepaid cards does not expire if you send at least one message every 3 months.
