You can show the value using below code in,

/app/code/Vendor/Module/etc/frontend/di.xml

<?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"/>
 </type>
</config>

app/code/Vendor/Module/Plugin/Block/Checkout/LayoutProcessor.php

<?php
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)
 {
 $jsLayout['components']['checkout']['children']['steps']
 ['children']['shipping-step']['children']['shippingAddress']['children']['shipping-address-fieldset']['children']['telephone']['value'] = '+91';
 return $jsLayout;
 }
}

• aravind: Try my updated answer..Remove checkout_index_index.xml
• Purushotam Sharma: Not working , Please also review My updated question
• aravind: My updated answer is working one. I have tested, but it will be displayed directly inside telephone number field and not in separate box.
• Purushotam Sharma: I need in separate box So I set this with css before Phone number field
