problem with connecting to iPad on the phone app

An iPad, whether a Cellular model or not, is not capable of directly accessing Cellular Voice or Messaging features. An iPad with Cellular connectivity alone can only access IP-data services. An iPad is not, and can never be, a standalone substitute for an iPhone.

However, when coupled with an iPhone, the capabilities of iPad significantly broaden to include access to Cellular Voice and Messaging services of the associated iPhone - relayed to the iPad over WiFi using Apple’s Continuity features. For the most part, an iPad using Continuity is able to access Cellular calling features, of the iPhone, when both the iPad an iPhone are in close physical proximity and are connected to the same WiFi network - but this is not the end of the story.

The settings that you need to change/verify on your iPhone and iPad are:

On your iPhone

Settings > Mobile Data >WiFi Calling > 

• WiFi Calling on This iPhone - set to ON
• Add WiFi Calling for Other Devices - set to ON

Settings > Mobile Data > Calls on Other Devices > 

• Allow Calls on Other Devices - set to ON
• [Allow Calls On] - explicitly enable your new iPad from the list of devices.

On your iPad

Settings > FaceTime > Calls from iPhone > Calls from iPhone - set to ON

Additional information about Continuity and the relevant Cellular services can be found here:

Your Samsung phone does not integrate with your iPad's calling or messaging features.

To make or receive cellular voice-calls, or access SMS/MMS messaging, you will require an iPhone.

An iPad cannot make cellular calls.

An iPhone can make cellular calls.

An iPad can ask an iPhone to make a cellular call via a feature called Continuity, when both are signed into the same Apple Account.

Your Samsung can make cellular calls, but is not relevant to any of this: no Continuity support, no Apple Account.

You need an iPhone to make this work.

To use Apple's Continuity services, both your iPad and iPhone must be signed-in to iCloud with the same Apple Account (AppleID).

Have you verified with your cellular carrier that your plan supports Wi-Fi Calling? (It might be "plans" if your iPad and iPhone are on different contracts. I hope they are with the same carrier.)

Samsung phones won’t show on an Apple Account. Not outside of maybe a music subscription.
