What is RoamSIM Service?
It is a Prepaid SIM Card service that is specially designed for use by the
international traveler. It offers the advantage of low-cost per minute rates
for calling any fixed line or mobile number anywhere without the exorbitant
roaming charges that are ordinarily imposed on calls made from a roaming
handset. It is a service supported by best-of-class tier-1 GSM operators
offering high-quality reliable services. With RoamSIM you have all the standard
GSM services including Voice Mail and SMS. There is no significant delay or
inconvenience in the use of RoamSIM to make a call. Receiving a call by the
RoamSIM is exactly the same as with a regular GSM SIM card; the important
difference is that with RoamSIM you achieve great savings.
How does the RoamSIM service work?
When you dial a telephone number from a roaming GSM handset equipped with
RoamSIM and press SEND, the RoamSIM signals its home GSM operator (i.e. the
operator that issues the RoamSIM) to do the following:
(a) to call back the roaming GSM handset to the telephone number that is
assigned to the roaming GSM handset by the foreign (local) GSM operator of the
GSM network servicing the GSM handset
(b) to call the destination number that you have dialed
and then bridge (or connect) the 2 calls (a) and (b) to enable you to have
conversation with the party at the destination number.
The operation described in (a) and (b) above are transparent to the you, the
user, and you do not experience any significant delay in making the call. As
the call is dialed by your home GSM operator through its normal high-quality
carrier network, you would experience the normal high-quality service.
Can I do SMS text messaging with the RoamSIM?
Yes. RoamSIM incorporates current advanced SIM technology and supports all
standard features of a GSM service.
Does RoamSIM offer data service via 2G/3G network to the internet?
Yes. Use Prime profile in Italy and United Kingdom, and use Global profile in the rest of the world. Set the APN as "globaldata". Username and password are not needed. Refer to the mobile phone's manual for data service settings.
Is Voice Mail service available with RoamSIM?
Yes. All calls that are not answered after a certain number of rings
(programmable to suit) are automatically routed to a Voice Mail Server where
the caller can leave a voice message for the called party.
To retrieve the voice mail message, you simply dial 121.
There is a small per minute charge for accessing the Voice Mail Server plus the
air time at the per minute rate for calling a UK number.

How do I use RoamSIM and RoamSIM service?
RoamSIM service is very easy to use. It takes 3 steps:
Insert your RoamSIM into your mobile handset.
Switch on your handset and enter the PIN code provided
with the RoamSIM.
Your handset will automatically connect to an available
GSM network in the country.
For more information, see the RoamSIM Quick Start Guide.
Can RoamSIM work with any GSM handset?
No. There are a large variety of handsets available worldwide and some handsets
do not support RoamSIM's application. Additionally, some approved handsets may
have to be SIM unlocked in order to use a different GSM operators' SIM.
If dialing +<country code><area code><local telephone number> does not work, use +<country code><area code><local telephone number># or *<country code><area code><local telephone number>#, or 00<country code><area code><local telephone number>#.
Generally it is recommended to use a Tri-band handset. This is not necessarily because of the frequency coverage. It is more because Tri-band phones require a firmware set that is more standards-based and hence will perform correctly. Some cheaper Dual-band phones (which include Nokia 1112 and 1116 series, Motorola F series, Sony Ericsson K100 and Siemens C series) tend to use cheaper and lower quality firmware sets to achive their low price. This is not to say that they do not work, more that their operation can be unpredicatable.
Ensure that the phone supports the frequency band of the country where it will be used. Generally the frequency bands are
North America: 850, 1900
South and Central America: 850, 1900. Some countries mix in 900 and/or 1800.
Africa, Europe, Middle East, Asia, Australia: 900, 1800
Japan: 1700, 2100
And some countries have added or are adding 2100 for 3G. For specific country, please see maps.mobileworldlive.com.
What happens when you make a call?
When you key in the number you wish to call in the dialing format
+<country code><area code><local telephone number>
(or *<country-code><area-code><local telephone number>#
or +<country-code><area-code><local telephone number>#
or 00<country-code><area-code><local telephone number>#)
RoamSIM performs its special call routing operation. This operation may cause
your handset to display messages such as "number not allowed", "blocked call",
"invalid number" perhaps followed by "sending message". These messages are the
GSM handset's response to RoamSIM's call routing requests and are normal, and
you should disregard these displayed messages.
If you are using an approved GSM handset, you will get a callback call from the
home GSM operator, and your GSM handset will ring. You should then press the
"Send/Yes" key to answer the incoming call and hear a voice message that tells
you to wait for the call to be connected to the party at the destination
What would cause my approved GSM handset equipped with RoamSIM not be able to
automatically connect to an available GSM network?
A approved GSM phone with a RoamSim will automatically connect to any available GSM network in the area. In some countries there could be more than one GSM operator, and you may have to manually select a suitable GSM operator. You may also have to switch the current GSM operator if you are unable to receive a callback call after you have initiated your call. You should also verify that the SIM is using the correct profile: select "Italy/Prime" when in Italy and United Kingdom or select "Rest of the world/Global" when in any other country, or if the SIM has a USA profile (number) select "USA" or "Rest of the world/Global" when in USA or Canada.
Does RoamSim expire?
Yes. If a RoamSim is not used for 12 months, it will be deactivated, and any credit in the RoamSim will be forfeited.
What do I have to do to get to use RoamSIM service?
You have to do the following:
Note that RoamSIM is a prepaid service.
When there is no credit remaining in your RoamSIM account, you will not be able
to make calls using the RoamSIM service. The maximum duration to be allowed for
a call, that you want to dial, is calculated, based on the per-minute rate
according to the dialed destination number dialed and the available credit in
your RoamSIM account, by the RoamSIM system before the call begins.

How does mobile roaming work?
Roaming is defined as the ability for a cellular customer to automatically make and receive voice calls, send and receive data, or access other services when travelling outside the geographical coverage area of the home network, by means of using a network in the area visited.
Roaming is technically supported by mobility management, authentication and billing procedures. Establishing roaming between network operators is based on - and the commercial terms are contained in - Roaming Agreements. If the network visited is outside the home country, this is known as International Roaming.
GSM Roaming, which involves roaming between GSM networks, offers the convenience of a single number, a single bill and a single phone with worldwide access to over 210 countries. The convenience of GSM Roaming has been a key driver behind the global success of the GSM Platform.
When abroad and "Calling Home"
What actually happens when you "Call Home", and what are you paying for?
1. When abroad and "Calling Home" to a friend, your call is managed by the host operator.
2. The host operator passes the call via 'international transit' to your home operator.
3. Your home operator connects you to your friend's operator and establishes your call.
Who pays for what?
Steps 1 and 2. The host operator charges your home operator a wholesale rate which includes the interconnection costs ("International Transit" and costs for terminating the call) and its own network costs.
What you pay
Your next bill will include the above charges, plus other costs sustained by your operator (i.e. commercial costs, overhead costs, IT costs), plus a "profit margin" applied by your operator.
When abroad and being called from home
When a friend calls you from your home country, you are charged an international roaming price.
1. A friend calls you on your mobile phone while you're roaming
2. His operator routes the call initially to your home operator (which may or may not be the same)
3. Your home operator forwards the call to the host operator you are currently roaming on in the destination country, via 'international transit'
4. The host operator receives the forwarded call, connects you using its network and establishes your friend's originated call
Who pays for what?
Step 1. Your friend will be charged a normal call by his home operator for calling you.
Steps 2 and 3. Your home operator will charge you a tariff which includes inter alia the international transit fees to forward the call to you in the destination country and the cost for terminating the call on the host network.
Your friend pays the standard national rate (step 1).
You as a roamer pay the above charges (steps 2/3), plus other costs (i.e. commercial costs, overhead costs, IT costs), plus any additional charge to provide a reasonable return on investment by your home operator.
