Yes. Once you have implemented the necessary technical and billing & transfer information related to each of the members, and vice versa, you will be able to receive roamers from all the Link2One community operators. Your subscribers will have access to the member networks and increased roaming connectivity as a result.

The services in place are voice, CAMEL, GPRS/3G/HSPDA and SMS roaming.

It depends on your network set-up, but it should take you around three hours per operator connected to the Roaming Hub. After the launching date, the roaming service is then ready for use in your new implemented connections which will  be checked in the monthly QoS testing.

The hub platform is able to manage all three CAMEL phases, but it depends on what the VPMN supports. We provide information about what other connected operators support, but as is the case for bilateral roaming, we can't intercede.

The different available roaming services (GSM, GPRS, CAMEL) of each operator to be connected to Link2One will be tested only once by using a standard testing set, both for IREG and TADIG purposes. Link2One will be responsible to coordinate and assure that all this process is carried out properly.

All that is required is one SCCP connection to Link2One. Bilateral SCCP connections with each VPMN are no longer necessary. A change in your SCCP provider is not needed. You will only need to ask for connection to the Link2One network in order to reach the Roaming Hub platform.

Link2One is not a GRX/IPX provider. This means that each operator still needs to contract services from a GRX/IPX provider.

Yes, absolutely. Link2One does not complicate TAP exchange by using alias TAP codes, and Link2One is not part of the TAP flow. Run your business as usual without intervention.

Yes. You know exactly where your roamer is registered, and, for inbound roaming, you know the identity of the IMSIs registered in your network through the Hub platform.

Link2One does not get involved in IOT (interoperator tariffs) issues. Operators agree on IOTs, and these are completely unaffected by Link2One Hub operations.

Link2One generates and makes available online a commercial launch letter for each new roaming service connected through Link2One. Link2One members should notify their data clearing house, financial clearing house and near-real-time roaming data exchange agent about new relationships they open through Link2One.

Yes, there is absolutely no problem. You are in control. Link2One has an established and defined process to manage your roaming relation migration. You only have to advise L2O with time enough to prepare and update systems.

Yes, there is absolutely no problem. You are in full control of all your roaming relationships and can establish them exactly as you want to, either bilaterally or through the Hub. Link2One has an established and defined process to manage your roaming relation migration.

In general, it is not possible to have both services for the same destination. When you connect to a roaming partner through Link2One, you must block the dual IMSI service for that particular roaming partner.

Operators can use their existing roaming tools in the same way as they do for bilateral roaming relationships.

Yes. When launching a relation through Link2One, you need to ask your NRTRDE provider to start exchanging NRTRDE files at the launch date of the relationship.

An operator provides just one set of test SIM cards to Link2One instead of test SIM cards to all partners. This minimizes expenses as well as maintenance efforts for test SIM cards. As numbers of test SIM cards are drastically reduced compared to bilateral relations, the related fraud risk is also minimized.

It is in the interests of all the users of Link2One to facilitate roaming service with as many roaming partners as possible to generate additional revenue. Link2One has an agile community of members, we have members using 170 connections or more and the average member uses more than 80 connections. Nevertheless Link2One cannot enforce network opening.

Yes. If you are an MVNO (mobile virtual network operator) you can connect to the Hub to gain extra (roaming out) coverage, provided you have your own IMSI range and connectivity infrastructure.

The Roaming Hub functionality does not interfere with any change or analysis based on the MSISDN (Mobile Station International Subscriber Directory Number) of the roamer. This means that mobile number portability has to be handled in the HPMN (home public mobile network) just as it is in a bilateral relationship.

No. The Roaming Hub is not a substitute for your SS7 carrier, and your SS7 costs will increase in line with the increased traffic generated by Link2One.
