Frequently Asked Questions

  • 1. Do I need Wi-Fi or any other Internet connection?

    Nope! When power fails, the Wi-Fi will too. iSocket 3G is a cellular solution! You will need a SIM card though, please read below.
  • 2. Will iSocket 3G notify me when power is restored?

  • 3. How much will you charge monthly?

    Presently we only sell equipment and we do not offer connectivity (i.e. SIM cards) - nor do we charge for service (e.g. access to our apps). iSocket 3G is not locked into any certain provider. You only pay to your SIM card supplier. For some countries you need to choose your network before purchase. See also: "Why do you ask for my network?". Simple answer: we will not charge you monthly.
  • 4. I am a Verizon/Sprint (USA) customer. Will iSocket work for me?

    Absolutely! If you have a Verizon/Sprint (USA) phone you can manage iSocket. The device and your phone are independent of one another. It doesn’t matter if you are a T-Mobile, AT&T, Sprint or Verizon customer – iSocket has no agreements with operators. To put it simply: there will be no problems if you are a Verizon or Sprint customer, but you will need a SIM card for iSocket. See below.
  • 5. Why does iSocket 3G require a SIM card?

    When you buy a phone or any other device with a cellular connection (e.g. Kindle) in the USA you often do not need to buy an additional SIM card, because connectivity is already uploaded to a SIM card installed inside the device or to a chip in the device such as for Verizon phones. For these devices you usually pay a monthly service fee. These are sometimes called locked phones. Since iSocket 3G works through the cellular network and is not locked to any operator, it needs connectivity to be able to send and accept text messages, call or send data. To provide connectivity to iSocket you need to insert a SIM card to a special slot for this card. SIM card has a phone number. You can then text or call to this number in the same way that you call or text to another cellular phone.
  • 6. What SIM card would I need for the U.S.?

    We do NOT charge any monthly fee from you, we only sell you a piece of perfect equipment for power monitoring - iSocket. You will need a micro SIM card for iSocket to get it work with cellular networks in the U.S. Only AT&T and T-Mobile support "bring your own device" option for iSocket. You are NOT required to be their customers though. Regardless whose customer you are, you have several options. Verizon customers have a solution too - read below.

    Most of our US customers use Truphone prepaid SIM because they don't charge monthly fee. You can buy them online with free shipping within US (note, when they ask to select a state, they mean the state for the number of your future SIM card, not for the shipping address). You only pay $15 for the card (for the plastic, one time) and $15 for the airtime which does not expire. When iSocket 3G sends alerts to you, this is considered an outgoing text. Each message costs 9 cents from that pre-paid airtime. You can later top up the credit (airtime) on the SIM card online via your Truphone account. Activation is also very simple. With that SIM iSocket will work on AT&T network.

    If you don't like Truphone SIM for some reasons or if they have changed their plans to the moment when you read it, then you can use other no-contract Prepaid SIMs. For instance, AT&T PREPAID SIM Card Kit will work with iSocket devices. There is no annual contract, no credit check for this SIM. You top up your balance on the SIM Card and pay as you go. When iSocket sends alerts to you, this is considered an outbound text. When iSocket receives a message from you (e.g. configuration command when you add additional numbers) - this is inbound text. Each text will cost you few cents from your pre-paid airtime. Your running cost expected to be around $3/mo because $10 credit will expire within 90 days, but this is quite good balance for your monitoring purposes, because it is about 100 texts. You won't have so many power outages for 3 month, don't you? Neither you need configure the device continuously.

    AT&T will ask you about IMEI number of the device during buying process. You can find it on the back label of the device - 15 digits below a barcode. We can tell you that number already after processing your order. If you buy it in a store, ask agent to help you with activation: they assign IMEI number of the unit to the number of your new SIM Cards.

    Anyone can use this SIM from AT&T, include Verizon customers. Similar Prepaid solution - T-Mobile 3-in-1 SIM Starter Kit - available from T-Mobile. SIM-cards from Verizon will not work, because Verizon's network is not supported by iSocket as for now. However, you can communicate with iSocket from your Verizon phone, you just need a SIM-card *for* iSocket, for example, one of the listed above. Or read below.

    There are other non-contract Prepaid SIM Cards that you can buy online available on the market, such as Black Wireless, H2O, Airvoice Wireless. Your running cost with these Pay-As-You-Go SIM cards will be around $3 monthly (because you pay $9 or $10 for 90 days). Again, it is enough for your monitoring purposes. These SIM cards use AT&T network. Black Wireless offers free fast shipping and simple activation process.

    One interesting prepaid option is SpeedTalk with some unlimited texting plans for one year. This works on T-Mobile network.


    Just buy Truphone Prepaid SIM mentioned in the beginning. Most iSocket units in the U.S. use this SIM. Contact us if you are still confused.
  • 7. What SIM card would you recommend for the UK and AUSTRALIA?

    For the UK if you have network coverage from Vodafone in the area that the iSocket will be installed, please check a Truphone Pay-As-You-Go SIM card. It has no monthly fee and the cost of a message is only 6p. For Australia you can use SIM cards from Telstra, Vodafone, Optus or their resellers. Of course, you are free to choose any other SIM cards that are suitable for your iSocket. See also: "Why do you ask for my network?"
  • 8. What SIM card will you recommend for CANADA?

    Our customers in Canada usually use 7-Eleven or Petro-Canada cards if they have network coverage from Rogers at the site, where the iSocket is installed. They use these SIM cards, because of the good price and simple activation. For some areas where Rogers is not available customers buy SIM cards from Telus, or Bell, or their resellers. You are free to choose, we do not lock iSocket to work with any particular network. You will need a Micro SIM card.
