Can I send international short messages when the mobile phone is not open for international calls?

Yes, you can send it directly to foreign mobile phones without opening the international long-distance function. International roaming means that mobile phone users can continue to use their mobile phones for voice, SMS and Internet communication in other networks in other countries and regions after leaving their home networks. At present, China Telecom has opened CDMA and GSM international roaming services with operators in more than 200 countries and regions around the world, and the roaming access range is still expanding. In these countries and regions, you can continue to use CDMA or GSM mobile phones for communication. During the roaming visit, China Telecom's global service hotline18918910000 provides 7×24 hours of free labor service. It is suitable for users of post-paid and pre-paid mobile phones (excluding wireless broadband) of China Telecom who have applied for Vodafone International Card. Note: prepaid mobile phones only provide prepaid C-G roaming service in Hong Kong and automatic roaming in Macao. If the three-way call service has been opened, you cannot apply for international roaming service at the same time. Tip: Users of 1, Hutchison International Card, Unicom Dual-mode Card and Ordinary Card need to change Vodafone International Card to open international roaming service. Users who have not cancelled the original international roaming function should change to Vodafone International Card as soon as possible. If they have not changed, they will not be able to deal with the problems in international roaming in time and effectively. 2. Confirm that the back of UIM card is Tianyi International Card (new) or Tianyi UIM card. If not, please change your card in the business hall. 3. The 3FF card for 3.iPhone4S, the NANO-sim card for iPhone5, the NANO-sim card for iPhone5S, and the iPhone5C are all Vodafone international cards, so there is no need to change cards for international roaming. 4. Telecom Samsung NOTE2 international roaming reminder.
