Mobile internet in Santiago de los Caballeros supports city maps, accommodation messages and onward transport. The same Dominican Republic eSIM used elsewhere can work where its permitted partner has coverage.
Santiago-specific guidance belongs inside the country connectivity plan rather than a competing network guide. Urban service can still weaken inside concrete buildings.
NoveSIM plans are data-only and do not add a Dominican number.
Quick answer: Save the accommodation and onward route offline, test the travel line outdoors before changing settings and use the country guide for the main connection decision.
