Receiving the Holy Spirit is a promise that is for all who have salvation in Christ.
Ephesians 1:3 Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ. 4For he chose us in him before the creation of the world to be holy and blameless in his sight. In love 5 he predestined us to be adopted as his sons through Jesus Christ, in accordance with his pleasure and will— 6 to the praise of his glorious grace, which he has freely given us in the One he loves. 7 In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God's grace 8 that he lavished on us with all wisdom and understanding. 9 And he made known to us the mystery of his will according to his good pleasure, which he purposed in Christ, 10 to be put into effect when the times will have reached their fulfillment—to bring all things in heaven and on earth together under one head, even Christ.
11 In him we were also chosen,[e] having been predestined according to the plan of him who works out everything in conformity with the purpose of his will, 12 in order that we, who were the first to hope in Christ, might be for the praise of his glory. 13 And you also were included in Christ when you heard the word of truth, the gospel of your salvation. Having believed, you were marked in him with a seal, the promised Holy Spirit, 14 who is a deposit guaranteeing our inheritance until the redemption of those who are God's possession—to the praise of his glory.
FAITH
Hebrews 11: 1 Now faith is being sure of what we hope for and certain of what we do not see.
When one repents of sin and accepts Jesus as Lord and Savior this person steps out in
FAITH knowing that if the tongues don't appear at the moment they receive salvation through Christ,
FAITH in Christ and his promise and his work on the cross is what it's really all about.Through Christ and Christ alone is where we find our forgiveness of sin and our salvation.
Now the Holy Spirit is to guide us into all truth and He only speaks of things about Jesus and not about himself
John 16:13 But when he, the Spirit of truth, comes, he will guide you into all truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come.
John 14:26 "But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all that I said to you.
So for the one's who have received salvation through Christ and do not speak in an unknown tongue have stepped out into
FAITH knowing that speaking in an unknown tongue is not what guarantees our salvation.The Holy Spirit is only sent to the ones who have salvation through Christ.
Jesus is the only sign that a believer needs to receive salvation.It's through the blood of the Lamb that saves a person and this alone is what
FAITH is about!
FAITH in Christ is what gets a person saved not tongues.
However I would love to have the gift of tongues but I don't but I have
FAITH that I have salvation because of Jesus.I wonder how many poor souls have begged for the Holy Spirit because they didn't speak in an unknown tongue when they were saved?What did Jesus say about this?
Matthew 14:31 Immediately Jesus stretched out His hand and took hold of him, and said to him, "You of little faith, why did you doubt?"
Matthew 17:20 And He said to them, "Because of the littleness of your faith; for truly I say to you, if you have faith the size of a mustard seed, you will say to this mountain, 'Move from here to there,' and it will move; and nothing will be impossible to you.
So I will put my
FAITH in Christ,secure in my salvation through him alone and if the Holy Spirit gives me the gift of tongues (YEA

Maybe another gift,such as discernment,maybe knowledge in the word?
