Before RCS number detection, first confirm whether the mobile phone model and operator support it

Also send with images, buttons and linksSome customers can receive RCS messages normally, while others can only receive ordinary text messages, and some numbers have not entered the RCS channel at all.

This difference does not necessarily mean there is a problem with the sending system.Whether RCS can be used normally depends not only on the mobile phone number, but also on the mobile phone model, operating system, operator support and whether the user has enabled relevant functions.

So, prepare to useWhen RCS contacts customers, it cannot just check whether the number is valid. A more reasonable sequence is to check the number status first, then confirm the device and operator, and finally complete the RCS number detection.

RCS is not available by default on all mobile phones

RCS can be understood as an upgraded form of ordinary text messages. It can support high-definition pictures, videos, links, buttons, read status, input prompts and other functions, and the display effect is richer than traditional text messages.

butRCS is not guaranteed to be usable just by installing a SIM card. It requires numbers, devices, operating systems, carriers and messaging services to work together.

Apple isThe official description of the 2026 update mentioned that using RCS on iPhone requires at least iOS 18, and the operator used by the number must support RCS services on iPhone. Availability varies by region and carrier.Apple's note on RCS

Android devices also differ. The mobile phone model is too old, the system version is low, the default messaging application is not supported, or the number is not completed.RCS verification may cause messages to fail to enter the RCS channel.

Therefore, it is detected that the customer is using a smartphone and cannot directly determine that the number can receiveRCS message.

The first step is to exclude invalid numbers

When the number has been stopped, logged out or cannot be used normally, continue to determine the device andRCS status has no practical meaning.

Use digital planetBefore RCS number detection, you can first complete the empty number detection to exclude numbers that have expired, are currently unavailable, or have obvious format errors. In this way, the subsequent analysis of mobile phone model, operator and RCS status is based on the valid number.

When organizing numbers, pay attention to the country code. International numbers lack national area codes, which is prone to errors in regional judgment and may also lead to operator identification andRCS detection is affected. Do not submit directly when you see the same number of digits. It is safer to unify the number format first.

If the number comes from an older advertising campaign, order data, or customer inquiry, also record the time it was obtained. A number that was valid several months ago may now be out of service or reassigned. Digital Planet's empty number detection reflects the current number status, and past results cannot be used permanently.

The mobile phone model determines the basis of the device

Once the number is valid, the next step is to find out what device the customer is currently using.

Digital Planet’s mobile phone model detection can help supplement device information and determine whether the number may correspond toiPhone or Android device, and know the specific phone model or device status. This result can be used as the basis for RCS support judgment, but it cannot be regarded as the final answer alone.

A new Android phone usually has betterRCS usage conditions, but the user may have changed the default messaging application or may actively turn off RCS. Even if older devices can make calls and receive text messages normally, they may not support full RCS functionality.

The same goes for the iPhone. The fact that the device is an iPhone only proves that the hardware belongs to the Apple system. If the system version does not meet the requirements, or the current operator does not provide RCS support, messages may still be sent via SMS or MMS.

In addition, after the user changes his mobile phone, the number can remain unchanged, but the device detection results will change. Long-term saved device tags are not suitable for direct use in the currentRCS judgment. Rechecking the mobile phone model through Digital Planet before official use can reduce misjudgments caused by old device information.

Carrier support is an easy thing to miss

Two customers use the same model of mobile phone,The RCS status may still be different, often due to the operator.

The operator to which a number belongs already supportsRCS, the operator where the other number is located does not yet provide the same service, and the final reception effect will naturally be different. Even within the same carrier, support coverage may vary across countries, regions, plans, or devices.

Apple's latestThe RCS notes also make it clear that availability will vary by region and carrier. If the RCS option does not appear in the phone settings, it may be that the current operator does not support it yet.

Digital Planet provides global operator detection, which can be found atBefore RCS screening, confirm the operator that the number currently corresponds to. After obtaining the current operator information, combined with the latest service range in the area, it is more reliable than relying solely on the number prefix.

Especially in areas where number portability has been opened, the first few digits of the number may not necessarily represent the current operator. After the customer retains the original mobile phone number and changes the operator, the operator label in the old information may have expired. Digital Planet's operator detection is suitable for supplementing the current status, and the original operator can be retained as a historical record.

After iPhone supports RCS, green bubbles need to be re-understood

seen in the pastMany people will directly interpret the green bubbles on the iPhone as ordinary text messages. This judgment is now incomplete.

According to AppleAccording to official instructions in 2026, RCS, SMS, and MMS messages may all appear as green bubbles on iPhone. RCS can also support high-quality pictures, videos, links, read receipts and input prompts, but it is not part of the iMessage blue bubble.Apple Message Type Description

Therefore, the green bubble does not necessarily mean that it is a traditional text message, nor can you judge whether the number supports it just by the color of the bubble.RCS.

If batch differentiation is required, it can be done through Digital PlanetRCS number detection separates numbers that support RCS from numbers that can only use ordinary text messages. The value of detection lies in selecting a more appropriate message channel in advance, rather than waiting until it is sent and then guessing based on the display effect.

What is a more reasonable order of detection?

The entire judgment process can beFour-layer advancement of "number, device, operator, RCS status".

First use Digital Planet to conduct an empty number test to confirm that the mobile phone number is still valid; then use the mobile phone model test to understand the device currently used by the customer; then complete the global operator test to confirm that the number currently belongs to the operator; and finallyRCS number detection determines whether this number has corresponding communication conditions.

If you just do it from the beginningRCS detection can also obtain the current related status of the number, but it is difficult to explain why it is not supported. After adding the device and operator information, you can further determine whether the mobile phone conditions are insufficient, the operator has not yet covered, or the number does not currently have RCS enabled.

These few tests don't need to turn into complex data engineering. Just keep the number, test date, phone model, current carrier, andRCS status can satisfy most practical judgments.

Detection results can be divided into different communication portals

The number is valid, the equipment conditions are met, the operator supports it, and the Digital Planet test shows that it hasThe number in RCS status can be reserved as an RCS entry.

The number is valid but not supported yetBeing a customer of RCS does not mean that the contact information has no value. You can continue to use ordinary text messages, or switch to WhatsApp, Telegram, LINE and other platforms based on the customer's authorized contact information.

If the equipment is older or the number is not currently covered by the operator, you can mark the detection date and wait for the service scope to be updated before rechecking. When the number has expired, there is no need to continueRCS try.

The point of this approach is not to exclude more numbers, but to allow each valid number to enter its own communication channel. supportUsing RCS, retaining text messages or other entries that are not supported is more reasonable than putting all numbers into the same sending process.

supportRCS does not mean it is suitable for direct marketing

The RCS status is normal, which only means that the number is qualified for receiving, but cannot prove that the customer is willing to receive commercial messages.

Apple has provided users with closuresRCS commercial messaging and spam reporting functions. Frequently sending content without consent will not only affect customer experience, but may also lead to reporting or service restrictions. Therefore, Digital Planet RCS detection is more suitable for existing customer notifications, order reminders, after-sales services, and information sending after authorization.

The content of the message must also be consistent with the user's original business relationship. If the customer only agrees to receive order notifications, it should not be automatically expanded to high-frequency promotions; if the customer has opted out, it should not beRCS detection shows support and rejoins the sending range.

RCS number detection determines whether the technical channel is available, and user authorization determines whether the message can be sent. These two matters need to be judged separately.

Whether RCS can be used normally cannot only depend on whether the customer has a smartphone. The number needs to be valid, the device and system need to meet the conditions, the current operator needs to provide support, and the client must also enable relevant functions. Through Digital Planet, the number, mobile phone model, global operator and RCS number detection are completed in sequence. You can see in advance whether each number is suitable for entering RCS, ordinary text messages or other authorized communication portals.
