At RoamSmart, we are here to facilitate the whole process for all stakeholders involved. We help Telcos (telecommunications companies) digitally transform their roaming and wholesale businesses and provide them with high-quality services that meet their specific roaming needs. Our solutions help optimize workflows and monetize existing roaming data from a variety of sources. To keep a long history short, we help create win-win partnerships for all parties involved and, most importantly, ensure end customer satisfaction. If you continue to spend more time abroad than at home and your roaming consumption continues to exceed your domestic consumption, your operator may charge you an additional fee for your use of roaming. Supplements (excluding VAT) are capped: the legal aspects of roaming negotiated between roaming partners for billing for services received are generally defined in so-called roaming agreements. The GSM association describes the content of these roaming agreements in a standard form for its members. With respect to the legal aspects of guest subscriber authentication, authorization and billing, roaming agreements can generally include minimum security standards, such as site update procedures. B or financial security or warranty procedures. This type of roaming refers to the possibility of joining the network of a foreign service provider. It is therefore of particular interest to tourists and international business travellers. Overall, international roaming is the simplest [ever?] with the GSM standard, as it is used by more than 80% of mobile operators worldwide. But even in this case, there may be problems, because countries have assigned different frequency bands for gsm communications (there are two groups of countries: most GSM countries use 900/1800 MHz, but the United States and some other countries in America have assigned 850/1900 MHz): for a phone to work in a country with another frequency allocation, it must support one or both frequencies of that country and therefore be sort or quad.
If international roaming allows the traveller to stay in touch during the trip, it can also result in considerable costs for users. Indeed, the use of mobile networks outside the country of origin can result in a large billing by the original mobile data operator.  Network elements that belong to the same operator but are in different areas (typical location where local licensing is common) depend on the switch and its position. Therefore, software changes and greater processing capacity are needed, but beyond that, this situation could introduce the fairly new concept of roaming on a msc basis rather than by operator. But it`s actually a burden, so it`s avoided.  Mobile operators can apply a “fair dealing policy” to ensure that all mobile subscribers travelling in the EU have access to roaming rules and benefit from “roaming and at home” rules (i.e. roaming services at home prices). This means that your mobile operator can apply fair, reasonable and proportionate controls to prevent customers from abusing the rules.
