SMS marketing in the United States,When registering an app or verifying an account, T Mobile SIM card adaptation is often the biggest headache for marketers. Many teams have found that using the same mobile phone number, some can successfully register, while others are stuck in the verification process of T Mobile. This process is not only time-consuming, but also affects conversion rates. So, how to screen out American mobile phone numbers that can pass T-card in advance? This article will break down the screening logic and efficient operation paths for you from a practical perspective.

WhyIs T Mobile card screening critical?

T Mobile is one of the three major operators in the United States, covering more than 100 million users. Because T Mobile has strict monitoring mechanisms for registration security, communication frequency, VoIP behavior, etc., many non-real or inactive numbers will be judged as unavailable in its system, thus affecting the efficiency of user registration or code reception.

In particular, the following types of behaviors will lead to"Unable to pass T card" problem:

lUse a virtual number or an inactive old number

lThe number is not bound to a real device

lquiltT Mobile labeled "Advertising Risk" or "Restricted Use"

Therefore, before large-scale marketing or account distribution, conductT Mobile adaptation detection is an extremely necessary action.

What characteristics can determine whether a number can pass?T card?

In extensive testing, we concluded the followingFour types of characteristics are key indicators that affect the T-card pass rate:

1. Real SIM binding record

Is the number bound to the real number?The SIM card, and being recognized as an active entity by the T Mobile system, is the primary judgment factor.

2. Communication activity score

Are there any recent text messages, voice messages orWhatsApp usage record reflects whether it is a normal number "in use".

3. Operator identification label

Whether it belongs toT Mobile official database (such as MCC/MNC code, network segment location, etc.), which determines whether the platform supports this number segment by default.

4. Blacklist detection situation

Even if some numbers have been available before, they will be pulled into the risk control list by the operator's system due to factors such as historical abuse, account bans, and code reception records. The screening tool must be able to check such numbers in real time.
