eSIMโOn Shop does not offer an unlimited data eSIM for Oman. Travelers can select from a range of fixedโdata plans instead. For example, the Om Oman 20GB 30Days plan provides 20GB of usage over 30 days, while the Om Oman 3GB 30Days plan supplies 3GB for a month. These options allow customers to pick a data allowance that fits their usage needs, and for highโvolume users choosing a larger fixed plan can be more economical than purchasing multiple smaller plans or using payโasโyouโgo alternatives.
