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
, 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
