No, inserting a data-only SIM typically does not affect your primary voice number if your device supports dual SIM functionality. You will retain your original number for calls while using the new SIM for data.
Is B4Travel compatible with all smartphones?
Most modern smartphones are compatible, provided they are carrier-unlocked. Always verify that your device supports the LTE or 5G bands used in the specific destination country before purchasing.
What happens if I run out of data?
If you exhaust your data allowance, speeds may throttle to a lower rate, or you may lose connectivity until the plan renews or additional data is purchased. Check the specific terms of your chosen plan for top-up options.
