Try the benefits from our GSM range, there are fewer telephone related costs associated with our GSM range, although call charges can be more expensive than land line calls. There is no line installation cost or any line rental charges. The Telguard GSM range requires either a Pay-As-You-Go or contract SIM card. It is recommended that a SIM from one of the main network service providers (Vodafone, O2, T-Mobile). Mobile fax and data must be enabled on the SIM, Vodafone and O2 are our preferred network service providers purely for the fact of seemingly better network coverage and quality of customer services experienced by us. Due to the fact Orange does not support fax and data we are unable to recommend Orange.
The costs of the calls are dependent on the tariff applied by the network service provider. Most calls will be well within 60 seconds so ‘by the second’ call charges are preferable. A single user or a small site would probably benefit from a PAYG SIM while a multi user site would be advised to use a contract SIM. The contract SIM will have a number of free minutes as part of the ‘package’ making calls from the Telguard free up to the air time provided.
The key to finding out how many minutes to get on the contract SIM is to use a PAYG initially and at the end of the first month the amount of credit used will give an indication of how many minutes were used and so a contact SIM can be purchased to cover the call pattern.
As with the call charges associated with a land line system the calls from a GSM system at a multi user site would be paid as part of the communal service charge. It is important to remember that the Telguard GSM does not store any numbers or information on the SIM. All the telephone directory information is stored on a separate nonvolatile memory on the circuit board. When the system is finally up and running the costs associated with keeping hard wired entry systems operational over their life span are high. If the labour cost of installation could be removed along with the cable that will need to be replaced at some point and also remove the static intercom handsets then surely the cost of door entry as a facility will be reduced. Enter the world of Telguard. Our range of systems do just that – reduce installation costs, the need for cable all over the building and the cost of maintenance.
