Packet Media supplies several installation options. Customers having larger capacity gateways tend to prefer installation in equipment racks, and the smaller capacity gateways tend to be units that stand alone and can usually be wall-mounted if required. The rack-installed gateways need a 3U space.

All models work on a 240V single phase electrical supply.

Connection is established just as by a normal mobile phone. The nearest mast for the selected mobile network picks up the signal emanating from the aerial attached to the gateway.

Packet Media supply the aerial as part of the equipment. The larger aerial installations tend to have a directional aerial, but many don't need one. Our engineers will recommend the most suitable aerial setup for your local circumstances. If you have a rack-mounted installation, the aerial combiner takes up a 2U space in the rack adjacent to the GSM Gateway.

The larger aerials can be mounted anywhere there is a good signal to the selected mobile phone carrier.

The aerial can be installed wherever there is a suitable signal there is no need to assume it should be on the roof, for example. There are limits to the length of the cable from the gateway to the aerial, depending on the gateway model, but we have never found any major problems finding a suitable place for the aerial. If necessary or more convenient, the GSM Gateway can be installed close to the aerial, because it doesn't need any special environment.

For small installations, the technical details can be handled over the phone. For large installations, our engineers will want to conduct a site survey first. Whichever route is taken, a technical specification for the equipment will be produced and used as the basis for a quotation.

The quotation can be used as the basis for a purchase order, and once we have received the order, we hand over to our Order Fulfilment Team.

To arrange the installation and commissioning, our Order Fulfilment Team will contact whoever in your organisation is most appropriate. If you have an external maintainer for your telephone system, they may need to be involved as well, so this is sometimes a 3-way arrangement.

On the day arranged, our engineer will turn up and install the equipment, test it and observe tests performed by you and/or your external maintainer. Once everyone is happy that the installation is up and working, you will be asked to sign an Installation Certificate.

You can then immediately report to the business managers that installation is complete, and your organisation is now saving money.

This will depend on the type of phone you own. Usually, the SIM is located behind the battery, and will slide straight out. To insert a SIM card you must first remove the battery door from the phone. You also must remove the battery ifself from the phone. Next, look for a square slot beneath the battery. Insert the SIM card into this slot with the gold metallic side of the sim card touching the metallic part inside of the slot

Yes, if you want to change phones you can do this very easily. Simply take out your SIM card from your current phone and insert it into your new phone. There is no need to purchase a new SIM card just because you are switching phones.

NO... each SIM card only works with phones that are compatible or unlocked.

A SIM lock, simlock, network lock or subsidy lock — not to be confused with PIN or PUK code — is a capability built-in to GSM phones by mobile phone manufacturers. Network providers use this capability to restrict the use of these phones to specific countries and network providers. Currently, phones can be locked to accept only SIM cards from one or more of the following:

- Countries (the phone will work in one country, but not another)
- Network/Service providers (e.g. Orange, T-Mobile, Vodafone, etc.)
- SIM types (i.e. only specific SIM cards can be used with the phone).

For further information please contact your network operator.

PUK stands for 'Pin Unlock Code', and has to be entered if you've locked your SIM by repeatedly entering the wrong PIN code. If you're asked for a PUK code, you've had more goes at guessing your SIM card PIN code than you're allowed. You'll need to phone your network provider Customer Services for your PUK code to unlock the SIM. For security reasons, it's only the network operator that can legally provide you with a PUK code to unlock your SIM.
