You can show the value using below code in,


<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Checkout\Block\Checkout\LayoutProcessor">
        <plugin name="ProcessReferrerConfiguration" type="Vendor\Module\Plugin\Block\Checkout\LayoutProcessor"/>



namespace Vendor\Module\Plugin\Block\Checkout;

class LayoutProcessor

     * Checkout LayoutProcessor after process plugin.
     * @param \Magento\Checkout\Block\Checkout\LayoutProcessor $processor
     * @param array $jsLayout
     * @return array
    public function afterProcess(\Magento\Checkout\Block\Checkout\LayoutProcessor $processor, $jsLayout)
        ['children']['shipping-step']['children']['shippingAddress']['children']['shipping-address-fieldset']['children']['telephone']['value'] = '+91';
        return $jsLayout;
