The table below shows how each service (anonymized as P1 - P5) fare in terms of conversion rate for each Pakistan (Middle-East) carrier. This data is used to answer the questions asked.
From Table 1, we can look at the data for each service to derive Table 2:
We look at Reliability and Sensitivity.
Thus in Pakistan (Middle-East), if you do not have phone verification service reliability data, you can pick an outright poor service, which results in bad user experience, and major loss of potential & existing users; there is a 15% difference in OTP reliability (between the worst and best OTP provider)
The effect of using a 2-service combination, is very obvious; the average Reliability across any 1-service is 71.84% (from Table 2 but calculation not shown) jumps to 77.13% (from Table 3a but calculation not shown) when any 2-service combination is employed.
The Sensitivity of any 2-service provide across 5 carriers is also less, i.e., OTP deliverability is more stable across carriers; the Sensitivity average & variance for 1-service combination is 24.11% and 0.059%, compared to that of a 2-service combination 6.12% and 0.0012%.
By selecting the best service (Table 2), the best 2-service combination (Table 3a), and deriving the measurements for 3-service combination (Table 3b), we create a Strategy table (Table 4) as shown:
Two-service and three-service combination is superior to one-service average Reliability by more than 2%.
Let us answer the questions posed about phone verification service in Pakistan (Middle-East):
In Pakistan (Middle-East), there are more phone verification services that has poor reliability across carriers because the phone infrastructure is less mature, and it is difficult for a phone verification service to be reliable across a large number of carriers. Thus choosing this right phone verification service is really crucial. In other words, don’t risk choosing a wrong phone verification service, use RingCaptcha because we know the best phone verification service/carrier combination for Pakistan (Middle-East).
For best practice, always use at least 2 services so that you can send a re-request for OTP, or auto-send an unconverted OTP through a fallback service. This is seldom done in practice because:
With RingCaptcha, you only maintain a single relationship with our SMS/voice OTP provider marketplace, develop for a single API, and you are never locked-in to any specific phone verification service. What is more we build in all these OTP fallback features plus fraud mitigation features so you don’t have to - you just make a single API call to send OTP, and everything else magically happens in RingCaptcha.
