Local SIMs have always been an important substitute for roaming services for those visiting other countries and particularly popular among regular visitors, migrant workers etc. Some Middle Eastern operators are building on the concept of a local SIM by offering a temporary local phone number which works in parallel with a user’s home number without the need for an additional SIM.
For example, Asia Pacific consumers are making use of roaming substitutes. They have adopted SIM-based alternatives to international mobile roaming across multiple regions in the Asia Pacific. Call-by-call substitutes to roaming for corporate and business users are already having a significant impact on the roaming market in Asia. As the usage of substitutes continues to increase, roaming prices will be reduced further. Certain substitutes may be more appropriate depending on national market conditions.
