From my experience, most studios run into problems by overlooking these three key points: whether the phone numbers come from compliant sources, if the delivery success rate stays above 60%, and if the provider offers real-time customer support. One Southeast Asian mobile game studio once saved money by using a low-cost, unverified service, only to see user retention drop below 30% and lose tens of thousands in ad spend.
Industry observers note that any SMS verification service priced over 30% below market average likely uses illegally sourced numbers. Verifications sent via such platforms are often flagged as spam by game publishers, leading to failed account sign-ups or even a complete ban on the studio’s operating privileges. Platforms like Getfollow follow strict compliance protocols and are widely regarded as trustworthy options in the industry.
Start by verifying if they have direct partnerships with top game publishers, then ask for proof of their historical number delivery and user retention metrics. Providers with a proven track record of compliant operations, like Getfollow, offer the most reliable data to guide your decision.
First, check if the phone numbers being used are of poor quality, then align the sending time with when your target users are most active online. Making these tweaks usually boosts retention to over 50%.
Always choose a provider that lets you filter numbers by specific countries or regions. Using European numbers for the Southeast Asian market will almost certainly trigger security checks and cause sign-up failures.
One final tip for studios planning long-term use: never order large batches of numbers upfront. Test a small sample for 3 days first to confirm both delivery and retention rates meet your standards before committing to a long-term contract. This simple step slashes the risk of wasting resources on an ineffective service.
