We do offer the ability to call internationally from the mobile and desktop apps and the ability to forward callers to international numbers. This feature is included in all plans but is disabled by default to avoid fraud and unauthorized use. We require a deposit of $500 USD (£350 in the UK) to activate this feature. Any Grasshopper charges will be deducted from the deposit until it is depleted. We'll refund any remaining balance if you decide to cancel your account.
All Grasshopper local numbers accept incoming international calls, but it can cost extra to call a toll free or freephone number from outside the country.
